Downgrade package
Check the latest updates in /var/log/pacman.log
. To downgrade a package, run (example of svt-av1
):
shell
sudo pacman -U file:///var/cache/pacman/pkg/svt-av1-2.2.1-1-x86_64.pkg.tar.zst
Then to prevent upgrade of that package, edit /etc/pacman.conf
:
txt
IgnorePkg = svt-av1
System cleanup
Every week, delete all cached versions of installed and uninstalled packages, except for the most recent three:
shell
sudo systemctl start/enable paccache.timer
Remove all the cached packages that are not currently installed, and the unused sync database:
shell
sudo pacman -Sc
Missing .so file
Search for package that installs a missing .so
file:
shell
pkgfile -s libcrypt.so.1
