Public bug reported:
do-release-upgrade has in its 2nd phase (as in 2nd block in history.log)
removed hundreads of packages which have not been displayed in the
initial "to be removed" list.
Amongth the removed packages are ubuntu-minimal, ubuntu-standard, ssh, parts of
x11 and also sudo. Killing the graphical environment during the upgrade (which
was done through ssh so it survived). Similar things have now happened twice to
me on 2 separate machienes, in one case on a 20.04->22.04 upgrade and once on a
22.04->24.04 upgrade both machienes did NOT have a problem with the other
upgrade they both where updated starting from 20.04 and ended at 24.04 in
succession. In both cases the problem was resolved by reinstalling a lot of
packages with apt install.
Obviously i must have done something uncommon or stupid to trigger this, but
even so, I do believe do-release-upgrade should not continue without warning
when for whatever reason ubuntu-minimal, ubuntu-standard,
ubuntu-desktop-minimal or similar packages are going to be removed. It would be
much easier for the admin to fix this if the 2nd stage errored out with an
internal error than if, as it happened many packages get removed and need to be
manually reinstalled on a half broken system
Again, iam not complaining that the upgrade failed, iam complaining that there
is no sanity check that stops before removing key packages like
ubuntu-minimal/ubuntu-desktop-minimal. Its much easier for the admin to look at
it and fix the cause than to have to recover a system that has hundreads of key
packages removed.
For the record, the root cause maybe was a 32bit openssh server on a otherwise
amd64 system for one of the boxes, for the other i dont know. but iam not
asking for that to be supported just for it not to have a catastrophic result
