[Bug 1783438] [NEW] Release Upgrader unable to determine upgrade

[Laurie]

Public bug reported:

I previously submitted https://bugs.launchpad.net/ubuntu/+source/ubuntu-
release-upgrader/+bug/1782849 and was advised by https://launchpad.net
/~brian-murray that bug was a duplicate of
https://bugs.launchpad.net/bugs/1069133 and that the reason I was
experiencing the issue was because I was using the oibaf PPA that
includes drivers that have higher version numbers than those provided by
the upgrade.

I purged the oibaf PPA from my system and downgraded drivers, however
I'm still experiencing the same problem. The upgrade won't work because
it's unable to determine the upgrade. Can someone please let me know
exactly which repos I need to re-enable and purge so I can get this
update sorted. Thanks in advance.
