** Description changed: [Impact] Many packages are not considered for removal by the release upgrader when upgrading from bionic to focal because gnome-software-plugin-snap is a part of the removal set but is not itself considered for removal. However, if you run 'sudo apt autoremove' after upgrading from bionic to focal you will have a lot of packages which will be auto removed. [Test Case] 1) Upgrade an 18.04 system with ubuntu-desktop installed to Ubuntu 20.04 (do-release-upgrade -d) 2) At the end of the upgrade choose to remove unneeded packages 3) When the upgrade has finished run 'sudo apt autoremove' and observe that the list of packages in comment #3 are all removable. With the version of the release-upgrader from -proposed the packages listed in comment #3 will be removed as a part of the upgrade process and will not appear in the list of packages 'sudo apt autoremove' wants to remove. - [Regression Potential] - While this change should only affect systems with the ubuntu-desktop or ubuntu-kylindesktop metapackage installed we should also test the upgrade of a different flavor (xubuntu-desktop) which depends on gnome-software-plugin-snap to ensure that it is not removed. - Additionally, we should ensure that nothing extra is autoremoved by collecting and comparing the list of packages installed after an upgrade with and without the dist-upgrader from -proposed. We'll want to make sure that only the packages that are in the 'sudo apt autoremove' list are not installed on the system that used the dist-upgrader from -proposed. + + [Regression Potential] + While this change should only affect systems with the ubuntu-desktop or ubuntu-kylindesktop metapackage installed we should also test the upgrade of a different flavor (xubuntu-desktop) which depends on gnome-software-plugin-snap to ensure that it is not removed. + Original Description -------------------- I've been testing some release upgrades from 18.04 to 20.04 and noticed some packages were not getting removed with the following in /var/log/dist-upgrade/main.log. 2020-09-07 15:57:38,148 DEBUG package 'libxml-sax-expat-perl' produces an unwanted removal 'gnome-software-plugin-snap', skipping 2020-09-07 15:57:40,290 DEBUG 'libxml-sax-expat-perl' scheduled for remove but not safe to remove, skipping 2020-09-07 15:57:40,349 DEBUG package 'libexporter-tiny-perl' produces an unwanted removal 'gnome-software-plugin-snap', skipping 2020-09-07 15:57:42,485 DEBUG 'libexporter-tiny-perl' scheduled for remove but not safe to remove, skipping In Ubuntu 18.04 this package was a part of the following tasks: Task: ubuntu-desktop, xubuntu-desktop, ubuntustudio-desktop, ubuntukylin-desktop, ubuntu-budgie-desktop However, for 20.04 it is a part of the following tasks: Task: xubuntu-desktop, ubuntustudio-desktop, ubuntu-budgie-desktop Because the package is in main it is not a removal candidate itself but given that it is no longer part of the ubuntu-desktop and ubuntukylin- desktop packages it seems reasonable to add it to ForcedObsoletes but only for those 2 metapackages.
