Hi! I have a trouble with [community] repository in pacman. When I try to install or update my installed packages, pacman returns this error message: [coirius ~]$ sudo pacman -S hwinfo error: could not open file /var/lib/pacman/sync/community.db: (Empty error message) error: target not found: hwinfo I tried to run 'pacman -Sy' but it's take no results ... Who known how to resolve this trouble? Thx.
