I want to setup a new virtual machine with some specified packages (name and version), that are provided.

For example apache2 in version 2.2.20-1ubuntu1 with all dependencies. Even if there is a new version of this package on the servers this one should be installed.

The solution has to work/scale with multiple (n) "setups". Another virtual machine might need an older version of apache2.

I currently know of some possibilities that install the exact packages, but do not scale that good:

  1. Copy all required *.deb to every virtual machine manually and enter: dpkg -i ... -> Could work, but it is very error prone. (Manual scripts etc.)
  2. Create and use a new Ubuntu repository for each setup. -> Does not work because I would need n repositories.
  3. Setup the machine once and copy the VM / create a snapshot. -> Does not work because I would need to store n VMs.

My problem could be labeled as patch management, but I do not want to update my packages to the current version. My goal is to install old packages.

You can use apt-get to install a specific version of the package a long as it is in an archive that apt knows about. From the apt-get manpage:

A specific version of a package can be selected for installation by following the package name with an equals and the version of the package to select. This will cause that version to be located and selected for install. Alternatively a specific distribution can be selected by following the package name with a slash and the version of the distribution or the Archive name (stable, frozen, unstable).

For example, you could do:

sudo apt-get install apache2=2.2.20-1ubuntu1

Note that you may need to do some dependency resolution on your own in this case, but if there are any problems apt-get will tell you what is causing them. On my 11.10 system I would need to do the following to get this to work:

sudo apt-get install apache2=2.2.20-1ubuntu1 \
                     apache2.2-common=2.2.20-1ubuntu1 \
                     apache2.2-bin=2.2.20-1ubuntu1 \

This helped fix a problem of mine. Thanks! – pthurmond Sep 20 '13 at 20:00
how to know which versions are available? – Rodrigo Gurgel Jan 25 at 15:51

To check which versions are available, you can check via:

sudo apt-cache madison ^apache2

Then copy the version or use the following syntax:

sudo apt-get install apache2=2.2\*

To check which version you've installed, run:

dpkg -l 'apache2*' | grep ^i

Thanks a lot for pointing out the =2.2\* option as a way to use a wildcard for selecting any available subversion. Thats what I wanted to know but didn't know how to ask :) – The Sexiest Man in Jamaica Apr 16 at 14:31
When listing the versions using dpkg -l <packageName>, the version number is sometimes truncated. To avoid this, use COLUMNS=100 dpkg -l <packageName> – CJBS Jun 10 at 17:57

Practically speaking, this isn't possible because the old versions are not kept in the archive, so unless you have a copy of the old version laying around somewhere, you can't install it. You should be asking yourself why you want to install an older version in the first place. On a stable release, the main reason for a new version being released is to correct a security vulnerability, and you don't want to be running a vulnerable server do you?

I need this to reproduce exact copies of old environments for development purposes. Is it possible to setup a mirror that does not delete old package versions to access the required packages or do I need to setup multiple repositories that only hold diffs? – ayckoster Jan 2 '12 at 14:57
@ayckoster, sure, you can run your own mirror, or just manually save all of the packages you install for later ( they are cached in /var/cache/apt/archives ). – psusi Jan 3 '12 at 0:37
@psusi: Not exactly a fair response, there might be many reasons. In my case the newer version might actually have a bug, and to double check that is the case the older version is needed. Just an example. – Cookie Mar 28 '14 at 21:23
@nomen, no, it is a single distro that does not use a rolling release model. Great care is taken to ensure that when critical bugs and security vulnerabilities are fixed in the stable release, that they do not cause regressions, but if it does happen, then file a bug report tagged with regression-release and it will be fixed or rolled back. – psusi Apr 5 '14 at 23:48
@nomen, if you want to make up your own meanings for words you will have a hard time communicating with others. For everyone else in the world, that is not what a rolling release is, and rolling release is the exact opposite, and thus, mutually exclusive with stable release. And now that I think about it, the original version shipped with the release is actually kept in the -release pocket, and updates go to the -updates or -security pocket, so while you can't go back to a previous update, you can go back to the originally released version. – psusi Apr 6 '14 at 1:17
