PPAs shipping a newer version of key system packages is a significant problem and leads to long and complex to identify bugs such as - https://bugs.launchpad.net/ubuntu/+source/ubuntu-release- - upgrader/+bug/2078376 + https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2078376 + https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2078418 + https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2078415 + https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2078391 + https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2078442 + https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2078445 We should not upgrade systems that have replaced system packages (or added packages that become core system packages) with PPAs. My proposal basically entails the following: * Identify seeded packages as "in main or has the Task field set". This is a bit lossy as not all seeded packages have the Task field set, but it is better than nothing. Alternatively we can embed seeds? * After we have rewritten the sources and disabled third-party repositories, bail out on upgrades if any of the identified seeded packages have a higher installed version than is available in the repository; this can be done by for package in cache: - if not package.current_ver: continue - if not <is seeded>: continue - cand = get candidate - if not cand.is_downloadable: - raise SomeError(f"The seeded package {package.name} is installed from a third-party repository or in an inconsistent state) + if not package.current_ver: continue + if not <is seeded>: continue + cand = get candidate + if not cand.is_downloadable: + raise SomeError(f"The seeded package {package.name} is installed from a third-party repository or in an inconsistent state) - - (Relying on the properties that (a) if the installed version is higher than the target release, it is the candidate and (b) if we disable the third-party repositories, it is no longer downloadable) + (Relying on the properties that (a) if the installed version is higher + than the target release, it is the candidate and (b) if we disable the + third-party repositories, it is no longer downloadable) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2078436 Title: Reject upgrades if packages are installed in a higher version than the target release To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2078436/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
