I ran into this bug when upgrading the HWE stack from Trusty (for the X server) and Utopic (for the kernel) to Vivid (for both).
What happened is that APT removed the packages xserver-xorg, xserver- xorg-core, xserver-xorg-input-*, xserver-xorg-video-* before moving on to install their Vivid counterparts, only somehow the following three packages were not removed, and therefore were left with broken dependencies, even though they were listed in the "will be REMOVED" section: xserver-xorg-video-all, xserver-xorg-video-ati, xserver-xorg- video-glamoregl. The persistence of xserver-xorg-video-glamoregl explains the error message. On my system the following three packages were also left with broken dependencies: xorg, libegl1-mesa-drivers, nvidia-340. I was also left without a working X server of course. I tried Andy's workaround but APT refused to run the first command (sudo apt-get remove xserver-xorg-video-glamoregl) because of the broken dependencies, and trying to remove all the broken packages (sudo apt-get remove xserver-xorg-video-glamoregl xserver-xorg-video-ati xserver-xorg- video-all xorg nvidia-340 etc) only led to more broken packages appearing and APT refusing to run the command. So I let APT fix everything: it reinstalled all that it had uninstalled in the first place (the Trusty X server): $ sudo apt-get -f install Then I could apply Andy's workaround: removing the offending package: S sudo apt-get remove xserver-xorg-video-glamoregl # this also removed xserver-xorg-video-ati and xserver-xorg-video-all and then re-running the HWE stack upgrade: $ sudo apt-get install --install-recommends linux-generic-lts-vivid xserver-xorg-lts-vivid libwayland-egl1-mesa-lts-vivid # the other packages are installed as dependencies Thanks Andy! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1480245 Title: package xserver-xorg-core-lts-vivid (not installed) failed to install/upgrade: trying to overwrite '/usr/lib/xorg/modules/libglamoregl.so', which is also in package xserver-xorg-video-glamoregl 0.6.0-0ubuntu4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server-lts-vivid/+bug/1480245/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
