Bug description:
Due to changes in systemd for bug 1849156 this issue now happens.
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.
