To verify that the "libsexy" problem was still there I restored my pre- upgrade situation and ran "sudo update-manager -d" again: the libsexy problem was still there.
I then restored my pre-upgrade situation once more, in "Software & Updates" changed the Download server from "http://nl3.archive.ubuntu.com/ubuntu" to the "Main server" and ran "sudo update-manager -d" again: step 3 "Getting new packages" took significantly longer but the libsexy problem was gone. Step 4 "Installing the upgrades" started alright but at about 2/3, shortly after the question whether or not /etc/udev/udev.conf should be replaces the screen went black and the keyboard went dead. When ssh'in from another box top told me that only the "xenial" executable was running. I issued a "powerdown" command to shut the box down while retaining the logs etc. Let me know what logs (if any) you would like to see. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1553483 Title: Can't install 'xubuntu-core' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1553483/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
