This is the verification work I did from a package management perspective, to verify correctness and consistency in a variety of scenarii:
1) In a fully up-to-date focal VM with enigmail, jsunit and tinyjsd installed, I enabled focal-proposed and updated: - from a terminal with `apt dist-upgrade`, debconf ncurses dialogs were displayed to notify of the removal of tinyjsd and jsunit from the archive - from the GUI (update-manager), debconf GTK dialogs were displayed 2) In a fully up-to-date groovy VM with enigmail installed, I enable groovy-proposed: - if jsunit and tinyjsd had been manually installed from focal-proposed (i.e. they are empty packages), they are not removed - if jsunit and tinyjsd had been manually installed from focal (release), they are removed with the upgrade 3) In a focal chroot without focal-updates, with enigmail, jsunit and tinyjsd installed, I hand-edited /etc/apt/sources.list to upgrade to groovy with groovy-updates and groovy-proposed and verified that jsunit and tinyjsd were being removed as expected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895643 Title: Backport Thunderbird 78 to 20.04 LTS and 18.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1895643/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
