I tried to install catalyst for my Radeon Graphics on 13.10 , but looks like everything went wrong . Now I can't install any software , and the software center says : The following packages have unmet dependencies: fglrx: Depends: libqtcore4 (>= 4:4.5.3) but 4:4.8.4+dfsg-0ubuntu18 is installed Depends: lib32gcc1 but it is not installed Depends: libc6-i386 but it is not installed xserver-xorg-video-intel: Depends: xorg-video-abi-13 but it is not installed I am a noob , thus I really don't know what to do . I tried to install lib32gcc1 and libc6-i386 via apt-get and it didn''t work also for unmet dependecies . I downloaded .deb package of libc6-i386 but I couldn't install it. any help ?
