Offline Package Management for APT

Posted by riteshsarraf on Sat 24 Oct 2009 at 14:43

This article is about Offline Package Management in Debian. Debian is a pretty well known project. One of the things that makes Debian very popular is APT (a.k.a Advanced Packaging Tool) which allows remote package downloads, upgrades and dependency resolution. Unfortunately it does require a network connection - unless you use apt-offline.

In Debian, when you need to install a package, you usually would fire up the apt-get command and the software would just install without any hand holding.

While APT is really very cool one of the main reasons for its success is the Debian Policy. The Debian Policy is like the brain of the project that controls the entire project ensuring that all the bits and pieces fit well together upto the Debian Standards. APT is just a result of the fantastic Debian Policy work.

In Debian, every package is very well self-contained and is tightly related to each other using APT. APT does a very good job of integrating and resolving dependencies for Package Management and takes off all the Dependency Hell problems from the user.

This is where the problem starts - for a machine which has network access it works very well because APT generates the list of packages and their dependencies and is able to download and install them successfully.

But when it comes to downloading a package individually on a different machine, along wih resolving any dependencies this can be a big problem.

Consider this real world example: I have a Debian box at home. At home, I have no (or very slow/expensive dial-up) internet connection. At work, I (or my friend) do have a very fast connection but (as part of IT policy) am required to use Windows.

I would still like to be able to painlessly update/upgrade my Debian box at home, with all the power and flexibility of APT.

This is where apt-offline is useful. apt-offline is an offline APT Package Manager.

Using apt-offline:

  • You generate a signature on your Debian box at home and carry the signature file on a removable medium (Probably a USB Stick).(e.g. "apt-offline set /tmp/apt-offline.txt")
  • Now you take the USB Stick (with the apt-offline.txt signature file) to the office machine which could be running any linux version, or as I mentioned above, even Windows.
  • There, you could run apt-offline giving it the signature file. (e.g. "apt-offline get C:\apt-offline.txt")
  • apt-offline would generate you an archive file or a folder with all the data. That data can be copied on a removable media. The removable media can be attached back to the disconnected Debian box at home and installed. (e.g. "apt-offline install /tmp/apt-offline.zip")

Let's start with a 3 step example

Step 1

Generate a signature file on the Disconnected Debian box at home

apt-offline set /tmp/apt-offline.sig

The above command will generate all information required from apt about updating its database.

By default, with no additional arguments passed, apt-offline will extract information about APT Package Database Update i.e. the --update option as well as the list of Packages to be upgraded i.e. the --upgrade option.

These options can also be individually passed if you want only one of those.

Step 2

Download data based on the signature file generated earlier

apt-offline get C:\apt-offline.sig --threads 5

The above command will download data as mentioned in the signature file. To speed up downloads (that can be from multiple apt repositories), in this example we spawn 5 download threads.

Note: It would be good to also download the bug reports for the packages that you are downloading. So that example now becomes:

apt-offline get C:\apt-offline.sig --bug-reports --threads 5

There are many more options that you can pass to apt-offline, like the --bundle option which would generate for you, an archive file with all the data.

Once completed, you could just copy the data (an archive file, if you used the --bundle option) back to the removable medium and copy it back onto your offline host.

Step 3

Once you're back upon the home Debian machine, you feed the data from the removable medium to apt-offline:

apt-offline install /media/USB/apt-offline.zip

This will update the APT database on your disconnected machine seamlessly.

If there were packages that needed to be upgraded, now they would all be available (with dependencies) in the APT database. So if you do an apt-get upgrade now, APT won't prompt you mentioning even a single bye download. APT would find that all required packages are already present in the APT cache.

If you had used the --bug-reports switch that I mentioned earlier, during install apt-offline would prompt you with the list of bug reports related to the packages on your machine that need be upgraded/installed - not just the list but the full bug report will be available for you to look at and evaluate the severity involved.

As you can see from the article above, apt-offline helps you achieve the power of APT, in just 3 steps. apt-offline is part of Debian and is developed at Alioth.

At the moment, apt-offline internally uses apt-get only.
My plans are to directly use python-apt if available. Support for aptitude is also planned, I just need to find out a way to generate the list of URIs in aptitude.

That's exactly what I wanted a few years ago. As it happens the PC I need it for now has fast network and I've migrated to using aptitude for all my upgrades now.

I can still see a need for this tool though, there is nothing worse than installing a box knowing that you have a nasty wait for the upgrades to come down a slow pipe - and a local cache of updated packages would always be useful.

Great guide but here's an error (I think):

The signature file is called apt-offline.sig on the first step and then on the next steps it's called apt-offline.txt

Thanks

How are you running apt-offline in windows exactly ? This is really a tool that might interest me, so I am curious of the windows part of the process. How have you been able to install it ?

There is only 1 method (i.e. Step 2) that can be run under Windows or any other platform. As you see in the example for Step 2, the path to the signature file itself is a Windows path.

Step 2 is the get operation, whose sole purpose is to only fetch the required data (debs, bug reports, apt package database updates) from the internet.

You will need python installed on the windows box. Then just download the apt-offline zip archive from the alioth project page, unzip it and execute it.

Its not necessary for Python to be _installed_...

At work (non-tech related business), users can not install applications on the PC and we're given a minimal amount of software of which Python is not included.

You can put Python on the same stick you plan to download to, and just add X:\<Python Directory>\bin to PATH and continue as normal.

Actually, instead of a build, you might just want to cd into the apt-offline folder and run your commands, like:

c:\apt-offline> python apt-offline set C:\set.uris

There were some minor issues with the setup.py file. They have been fixed and should be part of the next (0.9.7) release.

I am not sure why you are seeing this problem. I cannot see a reason why it cannot find out the module.

Are you installing it through the deb package that is available in Debian at:
http://packages.debian.org/search?keywords=apt-offline

From the screenshot it looks like, it is installed under /usr/lib/python2.5/site-packages/ but you seem to also be in ~/Desktop/apt-offline/ folder, which gives the impression that it might be an external installation.

Please file a bug report at http://apt-offline.alioth.debian.org in case you still see the problem.

How do you use this to install new packages? On my disconnected Linux I tried:

apt-offline set --install-packages rcconf -- /tmp/apt-offline.sig

and I get the following error: Couldn't find package rcconf

Looks like your apt database is empty on the disconnected Linux box. You first need to update the apt database.

For that, run:

apt-offline set /tmp/apt-offline.sig --update

It will generate the .sig file. Then run the get operation on the network machine. Then run the install operation on the disconnected Linux box with the data file.

Once the apt database is available, apt-offline will be able to generate the dependency for rcconf and its dependency packages.

Thanks for the fast response, that works. This is an amazing program. One note though, on windows "python setup.py install" had a syntax error with Python 3.1.1 but it worked with Python 2.5.4.

Thank you. You have uncovered a bug. And it has been fixed in my git repo.

Problem is, you have the cdrom repository enabled in your apt database. For now, if you want to use apt-offline, you will have to disable the cdrom repository in your apt sources.list and rerun the set command.

In the next release (0.9.8), apt-offline will check and skip the cdrom repository items. Thanks again for uncovering this.

Unable to use apt-offline at work. There was a oneline bug that we cleared up. But, the IT protocols won't let apt-offline download any files.

I can manually get the files one by one by using the url's in IE.

But, haven't a clue what to do with them once I get them.

Any pointers on how to assemble the files so that apt-offline can use them on the Linux side would be most helpful.

Thanks!

BTW: Supporting Linux in a non-net-connected system. So, we really need a way to get the updates on a locked down Windows Machine.

I cann't get the apt-offline work for me,I want install emacs,samba.But when I follow the steps,I cann,t install them too!
this is the way I did:
on ubuntu(no internet):
apt-offline set /tmp/apt-off-emacs.sig --release emacs
on windows(fast internet):
apt-offline get C:\\apt-off-emacs.sig --threads 2 (I got a folder)
back ubuntu:
apt-offline install /home/...(the folder)
and after a while when the apt-offline install command finished,nothing have been changed! After that I tried apt-get install emacs,nothing happened too!
so can you give me an example of how I get specific soft like emacs!
because I cann't find the example!!

Please follow the howto correctly. It will work.
from what you have mentioned, --release option requires a valid release, something like testing, unstable or stable.
So your correct command would be: "apt-offline set /tmp/apt-off-emacs.sig --release unstable --install-packages emacs samba"
More details available with: apt-offline set -h

I have the same problem here. I have followed the instruction to build the zip file. But, when I run "apt-offline install /home/username/apt-offline-filezilla.zip" It does not install the filezilla, instead, it only copy the filezilla packages into /var/cache/apt/archives directory. Is it the correct behavior of the apt-offline command? If so, how do I force apt-get to install the downloaded packages from /var/cache/apt/archives?
Here are what I did:

1. % apt-offline set /tmp/apt-offline-filezilla.sig --install-packages filezilla ( from laptop A w/o internet)
2. % apt-offline get /tmp/apt-offline-filezilla.sig --bundle /tmp/apt-offline-filezilla.zip --threads 5 (from laptopt B w/ internet)
3. % apt-offline install /tmp/apt-offline-filezilla.zip (back to laptop A)
4. Result: the filezilla packages were copied into the /var/cache/apt/archives directory by the apt-offline and apt-offline didn't install filezilla

any idea what went wrong? Thanks a lot!

Thanks for the reply! I ran "apt-get install filezilla", it seemed working. But then, I realized that I didn't disconnect the ethernet before I ran this command. So, I redo the steps again. This time, I got empty
apt-offline-filezilla.sig. No sure when I did wrong. Please help!!!

% sudo apt-offline set /tmp/apt-offline-filezilla.sig --install-packages filezilla

I ran this command from laptop with and without internet connection. Both cases generated empty apt-offline-filezilla.sig file.

I also checked /etc/apt/sources.list, it has all the default entries which was generated when I installed ubuntu.

I just ran it on my box and it generated the signature file.

Did you run the command on the box where the filezilla package is already installed? Or at least downloaded?

"apt-cache search" cannot locate package
Posted by VarunVats (116.203.xx.xx) on Wed 14 Mar 2012 at 09:43
Hi Ritesh,

I have a freshly installed Debian Wheezy box that cannot connect to the net (I have a USB modem, which requires packages usb-modeswitch and wvdial to be installed in order to use it, which unfortunately are not present in CD 1 ). However, on the same box I have Windows 7 installed in dual boot, which can successfully connect to the net. In order to install the above packages, I did the following:
  1. Ran
    apt-offline set apt-offline.sig --update
    
    on the Debian box and got the following message: Generating database of files that are needed for an update, which I assume is alright. I checked
    apt-offline.sig
    
    which had a lot of lines like http://......, which I think ar URIs for the packages.
  2. Ran
    apt-offline get apt-offline.sig --bug-reports -d apt-offline_dl
    
    on Windows. This gave me errors wherever the directory i18n was involved -
    Error - http://ftp.fr.debian.org/debian/dists/wheezy/main/i18n/Index.bz2 failed - probably because Index.bz2 does not exist. However, I am not too concerned about these as I believe they are translation files and are not relevant to what I want to achieve. I checked
    apt-offline_dl
    
    and found two files of size about 5MB.
  3. Ran
    apt-offline install apt-offline_dl --verbose
    
    on the Debian box and it completed without any errors. I also got the Great!!! No bugs found for all the packages that were downloaded. message.
  4. At this point I assumed that the cache was updated and ran
    apt-cache search wvdial
    
    However, I got no message. Looks like the cache was not updated. I also tried
    apt-offline set apt-offline.sig --install-packages wvdial
    
    which gave me
    E: Unable to locate package wvdial.
    ERROR:FATAL: Something is wrong with the apt system.


Any clues as to what could be going wrong? The following is my setup:
  • OS1: Debian Wheezy/Testing
    • Python: 2.7.2+
  • OS2: Windows 7
    • Python: 2.7.2
Thanks,
Varun Vats

Attached below is the apt-offline.sig file and the output with --verbose for each step.
  1. apt-offline.sig file: http://pastebin.com/zp3rp1A7
  2. Step 1 (set): http://pastebin.com/aZSEV29X
  3. Step 2 (get) verbose: http://pastebin.com/uQ0KSMBm
  4. Step 2 (get) errors: http://pastebin.com/d2grxAFb
  5. Step 3 (install): http://pastebin.com/9C1BHh2y
It seems like some of the errors in Step 2 (get) are due to wrong URIs. Like http://security.debian.org/dists/wheezy/updates/main/source/Sourc es.xz should rather be http://security.debian.org/dists/wheezy/updates/main/source/Sourc es.gz.

I just tried your .sig file here and it seems to be working fine.

The message in Step 2 is not fatal. It is just that your machine prefers the update files in .xz format where as the french debian mirror only supplies update files in bzip2 format.

Let me check further. I need to look closer into your logs.

Okay!! Nailed it out. You are the 2nd person reporting this issue. And both have seen this issue with Wheezy.

Seems like Wheezy has silently does some changes in the way they handle signing the update packages for the update files. I have it on my list but unfortunately haven't had the time to look into it.

Meanwhile, the workaround it to use the --allow-unauthenticated option in the install command

Thanks for the tip! It worked with the --allow-unauthenticated option! Sure this tool is going to come in handy when I do a minimal install once again!

Hi Ritesh,
I want to say thank you for helping people who don't have regular internet access with apt-offline.

Now on to the problem I ran into when trying to get it to work on Windows.
In Step 2 of this article you mention:
apt-offline get C:\apt-offline.sig --threads 5
But how am I supposed to get the program to work this way in cmd?
I ran the setup.py script, added apt-offline to the system environment variable Path and I still have to type:
python apt-offline
What's the problem?

Yes. You are right. I created the examples with Linux in mind. On a Windows box, only .exe, .msi, .bat etc are treated as executable. So, on Windows, you do need to prepend the command with the python executable. Thank you for pointing this.

Is this something that could be implemented in the future, so that Windows users can just enter apt-offline into the command prompt like Linux users?

Hello Ritesh,
apt-offline 1.3 seems to work well, but when I enter:
apt-offline install /media/USB/apt-offline.zip
The following error shows up:
ERROR: I couldn't understand file type extras.ubuntu.com_ubuntu_dists_raring_Release.gpg
Help would be greatly appreciated.

I haven't tested it with Ubuntu. This issue is related to the GPG integrity of the downloaded update files.

Can you run the same command in verbose mode?

Excuse the late answer, please.

I ran the same command with the --verbose parameter, but you didn't say which verbose messages you need, so I filtered some out:
VERBOSE: Namespace(allow_unauthenticated=False, func=<function installer at 0x957f8ec>, install='apt-offline.zip', install_src_path=None, simulate=False, skip_bug_reports=False, verbose=True)
Multiple messages printing:
VERBOSE: Cleaning data file
And then:
VERBOSE: {}
VERBOSE: Great!!! No bugs found for all packages that were downloaded.
ERROR: I couldn't understand file type extras.ubuntu.com_ubuntu_dists_raring_Release.gpg

Where can I do that?

You should file bugs against apt-offline @ http://apt-offline.alioth.debian.org

Regarding the log that you've pasted, can you confirm the version of apt-offline you are using? I think I fixed this issue some time back.

You may be hitting http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=664654

The version I am using is apt-offline 1.3 downloaded from Alioth.

I tried to file a bug report on Alioth, but it wouldn't let me register.
Check your apt-offline GitHub repository, as I opened an issue there.

Okay!! No probs. You can post the same on github. I'll see if I can setup an Ubuntu VM. But I can't promise when. So please just put all our conversation in the bug report. It'll help when we look back at it again, as time permits.


ERROR: I couldn't understand file type extras.ubuntu.com_ubuntu_dists_raring_Release.gpg.

Looking at the error, I was hoping it to be something similar to what I fixed some time back. The archive integrity management code keeps changing silently. So I'll have to look back at APT, on what new was introduced. Hopefully if it is a Debian issue too, I will be able to fix it quicker.

Thank you for reporting this issue.

Hello! Trying to use apt-offline for the first time and I am having some issues.

I went on my offline computer and generated a .sig file using:
apt-offline set /tmp/apt-offline.sig --update

Went on my connected laptop and used:
apt-offline get /pathtosigfile/apt-offline.sig --bundle /pathtosigfile/apt-offline-bundle.zip

When I returned to the offline computer and used:
apt-offline update /pathtobundle/apt-offline-bundle.zip

it said that their was nothing in the file?

No. But you need to be a little more tech savvy. apt-offline is written in Python. So you need to have Python installed on your Windows box.

Could I bundle it all into a self-executable .exe ??? Yes. But I really don't have the time for it. If you volunteer to do it, I may consider.

BTW, I still checked the docs. There's an INSTALL file, and it does talk about how to install apt-offline on Windows.

I started with apt-offline to only update some systems and it worked like a charm. Now, it's doing its job no longer with the same success rate. I'm using 1.3.1ubuntu1 and it seems to have a problem with automatically selected packages i.e.:

The following NEW packages will be installed:
linux-headers-3.13.0-36 linux-headers-3.13.0-36-generic
linux-image-3.13.0-36-generic linux-image-extra-3.13.0-36-generic

Ok, then let's try to add them manually with --install-packages option. I was lucky on the first system, however, failed on the second offline system. On that system apt still want to download some packages:

Need to get 60.8 MB/122 MB of archives.

I don't know, which packages are still to be downloaded and of course, why. Any help is appreciated.

BTW: the proxy parameters in the man page are wrong: --proxy-host <ip>:<port> is correct

Posted by riteshsarraf (27.7.xx.xx) on Tue 30 Sep 2014 at 13:38
Use both the options, --install-packages and --upgrade. Because it looks like you have some pending packages that need to be upgraded. As for the proxy feedback, please report issues on http://github.com/rickysarraf/apt-offline

My ultrabook doesn't have wifi driver. And it doesn't have an ethernet port even. It did not have apt-offline. So, I downloaded debian package for apt-offline (apt-offline_1.1.1build1_all.deb) in my online windows machine and depackaged into my offline ubuntu machine. Now when I try to generate apt-sig file. It generate and empty signature file and shows the following error.

Command run : sudo apt-offline set ./apt.sig
error: Command line option --simulate is not understood ERROR: FATAL: something is wrong with the apt system

I am running Ubuntu 14.04.1 LTS. Please help me to fix it so that I can install wifi driver in my linux machine.

That happens because we cycle through all available formats. What compression format is used on the archive is something the archive manager decides. For apt-offline (and apt), it is about trying all supported formats.

I understand that this message is misleading. Please file a bug report on the project page and I'll look into it later.

Request for a Wheezy backport of latest stable version
Posted by suspended user mefutatr (77.247.xx.xx) on Sat 3 Jan 2015 at 06:53
Hi Maintainer:

Thanks for the wonderful utility.

At the time of writing, the latest stable version is 1.5

Would it be possible for you to create a Wheezy backport of it? The official release of the stable version of Debian Jessie is at least 6 months away.

Does apt-offline work on Debian backports?
Posted by suspended user mefutatr (37.130.xx.xx) on Sat 3 Jan 2015 at 07:00
In your description of what your wonderful utility does, I am unable to tell whether it works on Wheezy backports.

In my sources.list, I have the following:

deb hxxp://YOURMIRROR.debian.org/debian wheezy-backports main

(I have replaced http with hxxp)

and I wish to install a package that is available from Wheezy backports.

Does your utility work?

Thanks in advance for your clarification.

This tutorial is great but it lacks the "apt-get install" step to trully install the needed package.

I was reminded of that in some recent exchange : https://lists.debian.org/debian-user/2015/03/msg00779.html
