build tests started failing after 42 Beta
On Ubuntu 22.04 Beta, the build tests started failing between 42.beta and 42.rc.0 and are still failing with 42.0.
You can find the build logs linked from https://launchpad.net/ubuntu/+source/gnome-calls/+changelog
I just did a test build locally and 42.beta still has passing build tests but 42.0 doesn't.
