I just want to revert i don't know how this happen
sudo pacman -Syy
error: could not open file /var/lib/pacman/sync/build.db: Unrecognized archive format
error: could not open file /var/lib/pacman/sync/core.db: Unrecognized archive format
error: could not open file /var/lib/pacman/sync/main.db: Unrecognized archive format
error: could not open file /var/lib/pacman/sync/apps.db: Unrecognized archive format
Yesterday internet was slow and broken, ok i understand what happen
sudo pacman -Rdd libcvt
sudo pacman -Suu
it's fixed, removing libcvt is better it can be removed xorg-server, but then should be explicitly installed then marked as dependant via pacman -Rdd xorg-server, -Sdd xorg-server, -D --asdeps xorg-server
