[Bug 2060578] Re: postfix installed during release upgrade to Noble

[Catherine Redfield]

We also see this bug running do-release-upgrade on GCE base VMs.  Prior
to running the upgrade and after running the upgrade, postfix is not
installed:

catred at jammy-to-noble-upgrade-arm64:~$ dpkg --no-pager --list postfix
dpkg-query: no packages found matching postfix


If I create a second SSH shell during the upgrade while paused on the postfix prompt, I see:

catred at jammy-to-noble-upgrade-base-amd64:~$ dpkg --no-pager --list postfix

The prompt I get is:
