I also tested upgrading an 19.10 Ubuntu desktop install with chrony installed to 20.04 LTS and chrony remained installed.

On an upgrade for people that had chrony installed on a do-release upgrade it now will: Calculating the changes MarkInstall systemd-timesyncd:amd64 < none -> 245.4-4ubuntu1 @un uN Ib > FU=1 Removing: chrony MarkDelete chrony:amd64 < 3.2-4ubuntu4.2 -> 3.5-6ubuntu3 @ii umU Ib > FU=0 That isn't what users want, those who had chrony installed would want to get chrony upgraded and systemd-timesyncd (which now is a separate pacakge) not installed. Test Case --------- 1) On a system running Ubuntu 19.10 or Ubuntu 18.04 LTS install the package chrony 2) Run do-release-upgrade with the appropriate switches 3) Observe that chrony is marked for deletion With the version of dist-upgrader from -proposed (accessed with the -p switch) chrony is no longer marked for deletion. Regression Potential -------------------- Given that Dimitri's change is now ignoring the tasks minimal and standard (which are handled by _keepBaseMetaPkgsInstalled) we should still be cautious and test desktop upgrades and ensure that packages in those tasks are not marked for removal. Regression Test --------------- 1) Run do-release-upgrade on an Ubuntu 19.10 or Ubuntu 18.04 LTS system 2) Record the list of packages marked for removal Compare the list of packages marked for removal with the release- upgrader from -proposed from Focal. Original Description -------------------- I'd ask you to revise the dependencies that got changes in systemd 245.4-2ubuntu1 so that on an upgrade from e.g. Bionic chrony stays installed as that was an opt-in chances are quite high people would want to keep it that way.
