I was unable to migrate from the Utopic to the Vivid stack with the provided commands; it seems that the --install-recommends breaks on some dependency to libegl1-mesa-drivers-lts-vivid, which is not installable.
My upgrade succeeded without the install recommends: sudo apt-get install linux-generic-lts-vivid xserver-xorg-core-lts-vivid xserver-xorg-lts-vivid xserver-xorg-video-all-lts-vivid xserver-xorg- input-all-lts-vivid libwayland-egl1-mesa-lts-vivid libegl1-mesa-lts- vivid libgbm1-lts-vivid libgl1-mesa-dri-lts-vivid libgl1-mesa-glx- lts-vivid libgles2-mesa-lts-vivid libgles1-mesa-lts-vivid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1479251 Title: E: Package 'libegl1-mesa-drivers-lts-vivid' has no installation candidate To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa-lts-vivid/+bug/1479251/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
