I tested the python-dbg scenario with the dist-upgrader from -proposed and that scenario continues to work and the upgrade is calculable.
** Description changed: Impact ------ Users with the package gnuradio-dev installed on their system are unable to upgrade from Ubuntu 18.04 LTS to Ubuntu 20.04 LTS as the upgrade is not calculatable. Given that changes to the python to python2 quirk have been previously made to ubuntu-release-upgrader we should ensure those previous test cases (LP: #1887544) still work. It isn't necessary to run the full upgrade go though, just calculating it should be sufficient. Test Case --------- [gnuradio-dev] 1) On an Ubuntu 18.04 LTS system install gnuradio-dev (or some set of packages which depend on it) 2) Run do-release-upgrade 3) Observe a message regarding the failure to calculate the upgrade With the dist-upgrader from -proposed there will be no such failure to calculate the upgrade. [python-dbg] 1) On an Ubuntu 18.04 LTS system install python-qt4-dbg (or some set of packages which depend on it) 2) Run do-release-upgrade - 3) Observe a message regarding a failure to calculate the upgrade + 3) The upgrade will be calculable. - With the dist-upgrader from -proposed there will be no such failure to - calculate the upgrade. + With the dist-upgrader from -proposed the upgrade should still be + calculable. [python-doc] 1) On an Ubuntu 18.04 LTS system install python-doc 2) Run do-release-upgrade 3) Say Y to removing obsolete packages 4) Observe that python-doc is still installed on the system With the version of the dist-upgrader from -proposed python-doc will not be installed after the upgrade and python2-doc will be. [python-dev] 1) On an Ubuntu 18.04 LTS system install python-dev 2) Run do-release-upgrade 3) Say Y to removing obsolete packages 4) Observe that python-dev is still installed on the system With the version of the dist-ugprader from -proposed python-dev will not be installed after the upgrade and python2-dev will be installed. Additionally, python-dev-is-python2 will be installed. Where Problems Could Occur -------------------------- As mentioned previously we could cause working upgrade paths with python- packages installed to failed. However, test cases have been added which cover those scenarios. SRU Team Special Note --------------------- This has not been fixed in Groovy because the code is not relevant for the upgrade path to Groovy. Original Description -------------------- Fails complaining about possible issue with PPAs. When these are removed fails with no complaints about PPAs or anything else. Just asks for bug to be reported. - ProblemType: Bug - DistroRelease: Ubuntu 18.04 + ProblemType: BugDistroRelease: Ubuntu 18.04 Package: ubuntu-release-upgrader-core 1:18.04.38 ProcVersionSignature: Ubuntu 4.15.0-118.119-generic 4.15.18 Uname: Linux 4.15.0-118-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.17 Architecture: amd64 CrashDB: ubuntu CurrentDesktop: ubuntu:GNOME Date: Fri Oct 2 17:14:41 2020 InstallationDate: Installed on 2016-09-07 (1485 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) - PackageArchitecture: all - SourcePackage: ubuntu-release-upgrader + PackageArchitecture: allSourcePackage: ubuntu-release-upgrader UpgradeStatus: Upgraded to bionic on 2020-10-02 (0 days ago) VarLogDistupgradeTermlog: -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1898152 Title: upgrade fails to calculate if gnuradio-dev is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1898152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
