Public bug reported: I tried running the upgrade, and it failed with this error. I saw the other bug https://bugs.launchpad.net/ubuntu/+source/ubuntu-release- upgrader/+bug/1767436 that seemed to be a related issue, however I went back and manually disabled any third-party repos I had setup in the sources list and tried again, to no avail. I got the same exact error after disabling those repos.
I was also previously using the https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers but I used `ppa-purge` to remove this before attempting the upgrade, as I've heard that it can cause a broken machine if not removed first.
