It seems likely to me that /run/user/nnn is provided if only because the
debian/tests/simple-tests seems to succeed, and that test requires key
generation and signing, both of which should use gpg-agent at least.

Indeed, gpg is brittle, and we might be able to identify some additional
brittleness, regardless of whoever's (good!) idea produced /run/user/nnn
If we can diagnose it, we should report back to upstream.  If
https://dev.gnupg.org/ is back up by then, opening an issue in the issue
tracker would be good.  otherwise, it's probably worth mailing
gnupg-devel at gnupg.org

I haven't been able to replicate the failure myself, but maybe someone
who can replicate it with incus could try it by increasing the logging
of the agent in that script and then looking at the artifact directory
produced by the failing test.

With the following patch to the gnupg2 package:

Then the debug logs should be visible in the CI artifact directory as:

If anyone manages to get any results (even if you don't know how to
interpret the gpg-agent logs), please follow up on this debian issue.

Thanks!
