[Bug 1069133] Re: Get upgrade error 12.04 - 12.10 "Could not determine upgrade" - xorg from ppa

[Sander Hollebrand]

Hi,

I managed to solve this error and do the upgrade from 13.10 to 14.04.

If you have the Xorg-edgers PPA enabled you have to purge it first, in
order to revert to the original config. However, I thought I just had to
remove the PPA from my software sources and be done with it. That didn't
work (which, in hindsight, is perfectly logical).

The  thing I tried after that was using ppa-purge of xorg-edgers. That
didn't work as well...because I removed the PPA from my software
sources. Duh.

So, I just added xorg-edgers to my PPA's again, used ppa-purge to
remove/revert and after that the upgrade from 13.10 to 14.04 went
flawless.

Long story short: you can only ppa-purge stuff that is in your list of
software sources.

Cheers,
Sander
