So...i need help with my installation of Arch Linux.
The problem is, every library is broken, and so is pacman-key --refresh-keys. I do have an installation medium that's bootable if it's needed.

(It all happened because i resized the partition that had a ext4 filesystem which is my root on it, without resizing the filesystem first. after mount gave an error, i resized it back. it did mount, but 3 errors from the EXT4-fs module popped up so i quickly unmounted it. after fscking it, it did become mountable again, but every library broke.)
