After trying to resuscitate the machine, it appears I have no term log. This upgrade wasn't even meant to be an actual test. After fixing the EOL 17.04 problem on my father's laptop and how horribly that went due to our ISP's service, I was attempting to see if it was the ISP or us causing grief.
During the two tries I went through to get things finished, multiple errors occured due to multiple packages contending over a single file that they wanted to overwrite. I got that straightened out with removals and breaks. Running do-release-upgrade left too many things from the 17.10 suite on the machine before this first problem which is where it stopped. Marking plymouth for reinstallation after I filed the bug resolved it. As to lsb-release, I now have this: skellat@Dreadnought:~$ apt-cache policy lsb-release lsb-release: Installed: 9.20170808ubuntu1 Candidate: 9.20170808ubuntu1 Version table: *** 9.20170808ubuntu1 500 500 http://ca.archive.ubuntu.com/ubuntu bionic/main amd64 Packages 500 http://ca.archive.ubuntu.com/ubuntu bionic/main i386 Packages 100 /var/lib/dpkg/status I didn't have anything screwy from a PPA installed in lieu of what rmadison shows as the available versions of lsb-release: skellat@Dreadnought:~$ rmadison lsb-release lsb-release | 4.0-0ubuntu20 | precise | all lsb-release | 4.0-0ubuntu20.3 | precise-updates | all lsb-release | 4.1+Debian11ubuntu6 | trusty | all lsb-release | 4.1+Debian11ubuntu6.2 | trusty-updates | all lsb-release | 9.20160110 | xenial | all lsb-release | 9.20160110ubuntu0.2 | xenial-updates | all lsb-release | 9.20160110ubuntu5 | artful | all lsb-release | 9.20170808ubuntu1 | bionic | all Since I'm missing the necessary logs this probably needs to be moved to Invalid. If somebody else sees it happen it can always be reborn in a duplicate marking. After four rounds resolving broken packages I'm at least left with this: skellat@Dreadnought:~$ lsb_release -a No LSB modules are available.
