@Brian: Here I am coming over from bug 1920829. I was at first tempted to comment in the original bug but the warning message on the page, "Remember, this bug report is a duplicate of bug #1069133. Comment here only if you think the duplicate status is wrong" prompted me to come here. So, here I am!
Unfortunately, I tried the ppa-purge route and failed: $ sudo ppa-purge ppa:oibaf/graphics-drivers Updating packages lists PPA to be removed: oibaf graphics-drivers Warning: Could not find package list for PPA: oibaf graphics-drivers $ When I looked online for ppa:oibaf/graphics-drivers, it appears that the packages in this ppa are no longer available for Bionic. I really don't know what "ppa-purge" actually does but what if the ppa is no longer available on the server? Is that why ppa-purge didn't work? Is there a way to get the missing package list somewhere else? If I can get hold of this list, where should it be located on my system and how can I get ppa-purge to use this specially-obtained list? Barring that, is it possible to just force a re-installation of the official packages that was altered when the ppa:/oibaf/graphics-drivers was installed? Is there a way to find out from the logs which packages need to be re-installed? I have a question open here as well: https://answers.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+question/696223 There is a plethora of additional information in this question. I would be happy if the correct answer appeared here or there! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069133 Title: Get upgrade error 12.04 - 12.10 "Could not determine upgrade" - xorg from ppa To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1069133/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
