The build fails now because the patch is missing.

I can't see the patch to compare. But does https://gitlab.gnome.org/GNOME/libcryptui/-/commit/b05e301d1b264a5d8f07cb96e5edc243d99bff79.patch apply cleanly? If so, you could also fetchPatch that patch.

Oops. I should pay more attention when using git.

The patch does not apply cleanly, because the release configure.ac only has gnupg 2.0, whereas the patch is against one that also has 2.1. We could also patch the patch or try finding the patch that adds that and apply both, but this option seemed the most straightforward.

Thanks, looks good! One thing I forgot to mention: it would probably add the removal to the list of Backward Incompatibilities in the release notes ( nixos/doc/manual/release-notes/rl-2009.xml ). Sorry for missing that in the first review!

I would argue that this is not a relevant enough change to warrant documentation in the release notes. This version was only used in one package, because it specifically checked for a version, but supporting anything newer didn't require any actual code changes in that package's source code.

It's also been unsupported upstream for years and the only reason that it wasn't dropped is probably that everyone collectively forgot it existed. IMHO the alias is enough.

(And yes, I admit it, I also really don't want to write XML.)
