Clear pacman cache
You can also define how many recent versions you want to keep. To retain only one past version use:
# paccache -rk1
Add the u switch to limit the action of paccache to uninstalled packages. For example to remove all cached versions of uninstalled packages, use the following:
# paccache -ruk0
