[Bug 1553483] Re: Can't install 'xubuntu-core'

[DLCBurggraaff]

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.
