To expand on that last comment, I'm including this message, which was returned from the terminal command
sudo apt-get upgrade -f ------------------------------- Unpacking fglrx (from .../fglrx_2%3a8.723.1-0ubuntu3_i386.deb) ... [Warning] Uninstall : inst_path_default or inst_path_override does not exist in /etc/ati. This suggests that the ATI driver is not installed, the ATI driver is only partially installed, or the current ATI driver is an older version than the one this script was designed for. Both files listed above are required for determining where installed files are located. To force uninstallation of the driver by guessing where the uninstallation files are located, set the FORCE_ATI_UNINSTALL environment variable and re-run /usr/share/ati/fglrx-uninstall.sh (this is not recommended). dpkg: error processing /var/cache/apt/archives/fglrx_2%3a8.723.1-0ubuntu3_i386.deb (--unpack): subprocess new pre-installation script returned error exit status 1 Errors were encountered while processing: /var/cache/apt/archives/fglrx_2%3a8.723.1-0ubuntu3_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1) -- package fglrx (not installed) failed to install/upgrade: https://bugs.launchpad.net/bugs/582636 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
