Just wanted to follow up as I was able to make some progress on this issue. While I don’t entirely understand the context, it seems that this issue is related to building on Minimal Ubuntu. The failing test cases begin to pass after `unminimize`ing the
OS in my case.

Unfortunately the mailing list never received your previous message:

Perhaps the attached log file is triggering some spam filters or going
over some size limit. Feel free to send it directly to me.

W/o the needed context, from what you say above, I'd assume the system
you are building on probably lacks some of the needed dependencies. If
so then perhaps the messages could be improved to make that more clear.
But perhaps the issue is something else, let's see from the log. :)

No worries!

I have attached the full testsuite.log at the end of this message.

Thanks, that was very helpful. (Although the mail didn't reach the
list either this time around, but I least I got it. :)

In case there are issues, the failure summary:

And all failures appear to be the same issue where the version command along with chdir option(s) result in the same extraneous exclude/include filters being set:

I verified this behavior outside of the test suite context by running
the binary with these options directly. And I got as far as adding
some trace logging to verify that these calls were indeed being made
to `filter_add` although I didn’t get much further than this locally.

Ok, this is a known problem, where dpkg uses the system-wide
configuration directory under /etc, where you have fragment config
files that interfere with the test suite. I guess I could filter-out
these specifically from the test output, but I was planning on working
on being able to set arbitrary config dir for dpkg after the release
that happened yesterday, so at that point this should stop being an
issue for this and a bunch of other stuff blocked on it.

Thanks,
Guillem
