Title:
  libomp5 got held back; `apt-get remove libomp5` allowed `sudo do-
  release-upgrade` to continue.

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  when running

      sudo do-release-upgrade

  I got an error message requesting that I run ppa-purge (I'm afraid
  that I no longer have the exact text of the error message). There was
  additional text that suggested looking at the contents of /var/log
  /dist-upgrade/main.log and /var/log/dist-upgrade/apt.log. The latter
  showed that libomp5 was held back.

  I checked the dependencies for libomp5, there weren't any important
  ones, so I ran

      sudo apt-get remove libomp5

  I was able to run the upgrade at that point.

  If I had been thinking, I would have gotten the output from

     apt-cache policy libomp5

  Unfortunately, I ran apt-cache policy, apt-get remove and do-release-
  upgrade in the same terminal, the upgrade overwrote my entire scroll
  back buffer, so I can't tell you what version I had installed.
