How can I downgrade a package to an older version via apt-get?
Other tools are also acceptable but apt-get is preferred.

If you have the version number, or the target release, apt-get supports choosing a particular version or target release. More details can be found on manual page of apt-get. It can also be accessed from terminal by typing man apt-get
sudo apt-get install <package-name>=<package-version-number> OR
sudo apt-get -t=<target release> install <package-name>
is the command to be run. This can be used to down-grade a package to a specific version.
Remark that when using a target release (option -t), the release priority must greater than 1000 to allow downgrades (see man 5 apt_preferences) otherwise the currently installed version will be kept.
It has been helpfully pointed out in the comments that
apt-cache showpkg <package-name> lists all available versions. (h/t Sparhawk)apt-mark hold <package-name> "holds" the package at the current version, preventing automatic upgrades. (h/t Luís de Sousa )Use:
apt-get install «pkg»=«version»
or:
sudo aptitude install «pkg»=«version»
Where:
«pkg» is the name of the package.«version» is the version number.If you have upgraded software using ppa you can downgrade it by using ppa-purge. First you have to install ppa-purge using this code:
sudo apt-get install ppa-purge
Then you can remove the ppa using command
sudo ppa-purge ppa:user/ppa-name
this will automatically downgrade the software to its original version which shipped with Ubuntu.
In my opinion, you should first uninstall or purge the package, like:
sudo apt-get remove <package>
or
sudo apt-get purge <package>
Then, you may download the version you would like to install and keep it in a folder, say abc.deb in Downloads. Open terminal, move to the folder using cd command and install the previous version using dpkg:
sudo dpkg -i abc.deb
Or else, there is a small utility called ppa-purge if you mean to downgrade packages updated via PPAs.
See this thread: http://www.webupd8.org/2009/12/remove-ppa-repositories-via-command.html
To downgrade you have to do a command like
sudo apt-get install pkg_name=version
in your terminal.
In the place of version put the previous version you want to downgrade to.
This question is old but Google led me here and I didn't find simple solution that does't require manual version passing when downgrading a bunch of packages to an older release.
So maybe someone who also needs that will find my solution useful as well.
There's a tool called apt-show-versions that shows versions installed. To install it:
$ sudo apt install apt-show-versions
Make sure APT's cache is up to date:
$ sudo apt-show-versions -i
You can easily downgrade all required packages by fine-tuning the regex but here it is:
$ sudo apt-get install $(apt-show-versions \
| grep -P 'newer than version in archive' \
| awk -F: '{print $1"/'$(lsb_release -cs)'"}')
You should have lsb-release installed for the latter.
