Hi,

Debian CI is switching away from lxc containers in favor of incus Containers.
This is motivated by security concerns from us; incus is based on lxc, but
orchestrates containers substantially different: containers are not privileged
(so root in the container is not uid 0 outside of it), and incus imposes a
stricter isolation from the host system).

sonic-pi passes its tests under lxc, but fails under incus.
The relevant part of the failure is (hopefully):
The full autokpgtest logs are available at:
https://ci.debian.net/experiments/8/regressions/
(please beware of pagination)

Common types of failure and suggested fixes are being documented at:
https://wiki.debian.org/ContinuousIntegration/LxcToIncus

Note that for the time being, sonic-pi is still being tested under lxc to
avoid disturbing its testing migration test results.

If you decide to add the `isolation-machine` restriction to get this package
tested under qemu, please mention that explicitly when closing this bug (it's
fine to do that only in the package changelog entry that closes the bug) so
that we can configure your package for qemu on ci.debian.net.

Hi, I was unable to reproduce this failure under local incus instance.
Is there some special container configuration used on Debian CI that I
need to apply here?

Hi,
https://wiki.debian.org/ContinuousIntegration/LxcToIncus

It's not just using incus, but using the same images as debci does,
which are minimal images (for reasons documented in the above wiki
page).

Thanks, I have recreated the image with debci 4.3 and the test failure
is now visible.

We believe that the bug you reported is fixed in the latest version of
sonic-pi, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1144838@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
