Had the same problem, and solved by executing this command manually, thus removing the xorg-drivers-fglrx instead of fglrx:
"sudo dpkg-divert --remove --rename --package xorg-driver-fglrx --divert /usr/lib/fglrx/libdri.so.xlibmesa /usr/lib/xorg/modules/extensions/libdri.so > /dev/null"
Afterwards, fglrx installs normally. However I still had a problem with the graphics card not being recognized, but this was solved after executing
"sudo aticonfig --initial"
After a reboot everything worked fine.
