Downgrade package version

[rodrigodlima]

Hi all,

As a security team issue, I need to be able to downgrade packages that have been updated. But I'm having problems with some versions of packages that are no longer in the repositories.
For example, I installed a new server Ubutnu Xenial (16.04 LTS) with a ISO media. The package wget installed was 1.17.1-1ubuntu1.2. Then, I update wget to version 1.17.1-1ubuntu1.3. When I tried to downgrade the wget for version 1.17.1-1ubuntu1.2, this version doesn't exists more.

# apt-cache policy wget
wget:
Installed: 1.17.1-1ubuntu1.2
Candidate: 1.17.1-1ubuntu1.3
Version table:
1.17.1-1ubuntu1.3 500

*** 1.17.1-1ubuntu1.2 100
100 /var/lib/dpkg/status
1.17.1-1ubuntu1 500

# apt-cache policy wget
wget:

E: Version '1.17.1-1ubuntu1.2' for 'wget' was not found

There is a way to install the last version for this package from some repository?

Look to see if the package is actually in your own system archive folder
look in /var/cache/apt/archives

Older versions of packages are archived at launchpad.net.
It's not a repository - you will need to download the package manually instead of using apt.
