Thank you for your response. I have run ``` ppa-purge ubuntu-toolchain-r ```
Which generates: ``` Updating packages lists PPA to be removed: ubuntu-toolchain-r ppa Warning: Could not find package list for PPA: ubuntu-toolchain-r ppa ``` However, I still get the same error when I try the distribution upgrade. I don't see ubuntu-toolchain-r in my sources.list. I also manually removed 3 files related to ubuntu-toolchain-r from my /etc/apt/sources.list.d directory. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813692 Title: Upgrade from 16.04 to 18.04 fails after disabling most third-party packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1813692/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
