I hope I reasoned why this is not useless. Co-installability is not our
worries here.

I think I wrote this too quickly. co-installability was of course the
reason for the versioned packages (that you suggested to get rid of).
The idea is that upgrades leave behind the old versioned packages (and I
have seen that happening), so you can still compile your programs with
the older versions if you want to. So I don't understand why apt tries
to remove the old packages. Do you know why? Because of course it is
possible that we made some mistake in the dependencies. Or could it be
that this behavior of apt changed sometime in the last years, or that
this behavior depends on an apt option?</pre><pre></pre></blockquote><div>I do have machines with more than one FPC versions and upgrades are just smooth.</div><div>Sometimes, old code doe not compile with a new compiler due to soem non backward evolutions, then users may want to keep old compiler until they port their code to the new version.</div><div><br></div><div>Also the breaks are only added when a substantial change in packages are made and this happened only a few times.</div><div>So stating that </div><div><span style="color: rgb(0, 0, 0); font-family: monospace; background-color: rgb(254, 254, 254);">fpc-$foo-3.0.4 Breaks </span><span style="color: rgb(0, 0, 0); font-family: monospace; background-color: rgb(254, 254, 254);">fpc (<= 3.0.4)</span></div><div>is a quick deduction I assume.</div><div><br></div><div>Can you please check with recent apt and let us know what exact upgrade scenario is failing?</div><div><pre><pre>-- <br></pre>Cheers,
