I couldn't make the only -x11 package installable, because of too strict guest-dkms dependencies (they need the same version as the x11 package).
So instead of fixing virtualbox everywhere, I'll just provide the guest-* complete stack for lts-utopic. virtualbox-lts-vivid - 4.3.34-dfsg-1+deb8u1ubuntu1.15.04.1~14.04.1ubuntu5 should be fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1424769 Title: virtualbox-guest-x11 uninstallable with mesa-lts-utopic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1424769/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
