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
