Thank you for taking the time to report this bug and helping to make Ubuntu better.
The error message says " This was likely caused by: * Unofficial software packages not provided by Ubuntu. Please use the tool 'ppa- purge' from the ppa-purge package to remove software from a Launchpad PPA and try the upgrade again." I can see packages in the listing that aren't from Ubuntu repositories, plus many PPAs where they could have come from. The error message you received fits, and the fix is `ppa-purge` i believe as the error message states. As such I've marked this bug invalid. If you believe i'm in error, please return status to 'New' and leave a message as to why you believe I'm in error. The fix is to remove your added 3rd party packages, then try the upgrade process again. If you need help removing these packages, I'd recommend looking at https://discourse.ubuntu.com/t/community-support/709 for possibly support options. Thanks again for trying to help us make Ubuntu better. ** Changed in: ubuntu-release-upgrader (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1840732 Title: Upgrade 18.04 LTS to 19.10 fail and rollback To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1840732/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
