Downgrading packages in Arch Linux

Arch Linux is a rolling release ditro and sometimes things get broken and need to be downgraded.

There are several ways to that, but the easiest is installing from the package cache. cd to the cache dir:

cd /var/cache/pacman/pkg/

Find the version of the package that you want to downgrade to and install it using pacman:

pacman -U <file_name_of_the_package>

If the cache was cleaned, you can download a snapshot or rebuild the package following the steps decribed in the Arch Linux wiki.
