https://bbs.archlinux.org – Problem solved. This was the result of messing up the permissions of the files when I copied them over from my hard disk.For future reference: whenever using cp to back up a partition, be sure to use the -a flag which preserves permissions![Partial] solution: Run the following commands:chown root:root /usr/bin/sudo     <---- make sure root owns sudochmod 4111 /usr/bin/sudo          <---- set correct permissions *and* set the uid bit to 1chmod 4111 /bin/su                    <---- same for suUnfor (HowTos)
