KFAIL is "known failure" similar to that in GNU development (gdb, etc.).
Bookworm uses it since its initial introduction because the upstream is not
stable, so it's still valid IMO.

We could convert bookworm to fail (by dropping try-except and calling
self.perform_build_test() directly); in that case, any upstream problems would
have to be analyzed quickly, and we might have to wait for upstream fixes. For
our maintenance work, we'd have to implement some support for local KFAIL
tagging.

The issue is seen in http://ci.isar-build.org:8080/job/isar_next/1328/console
(green due to KFAIL), but not in earlier runs.

Wow, I'd expect they'd have update-alternatives for that, but seems they don't.

We've started testing this, but I wonder how this works. When I debootstrap
bookworm, it picks python3-distutils and installs python3.10.

Bitbake 1.50.4 has been picked as the last tagged version before overrides
syntax change. Please let us know whether bitbake 1.50.5 works; in that case we
wouldn't have to swim against the upstream.


With kind regards,
Baurzhan.
