Ah, the avif codec must have been moved to a different codec package and that causes problems during the upgrade.
I will need to figure out how to tell dpkg to remove xpra-codecs before installing the newer split packages.

Yes, that's what 90a26b7 does, we'll see how it goes.

In the meantime, you can just remove xpra and re-install it, it should work.
