Hi!

I'm running the following commands on a arm64 GitLab shared runner node:

export LC_ALL=C.UTF-8
apt-get update
apt-get install -y guix podman ca-certificates
(guix-daemon --disable-chroot --build-users-group=_guixbuild &
guix pull --url=https://gitlab.com/debdistutils/guix/mirror.git \
 || (ls -la /var/log/guix/drvs/*/*.drv.gz; zcat /var/log/guix/drvs/qz/9fsb0935lpyssgg9428w9rvsypbfgv-cmake-bootstrap-3.24.2.drv.gz)

I get a build failure regarding "cmake-bootstrap" shown here:

https://gitlab.com/debdistutils/guix/container/-/jobs/8717616613

I cannot reproduce this on my own arm64 machine running Trisquel.

It seems only cmake's DEB related self-tests fail:

The following tests FAILED:

	562 - RunCMake.CPack_DEB.DEBUGINFO (Failed)

Errors while running CTest

That make me believe that the minimal nature of the container has some
impact.  Maybe some missing environment variable or tool or something?
That is usually present during normal builds but not this build.

The first failure starts here:

https://gitlab.com/debdistutils/guix/container/-/jobs/8717616613#L1746

with output cited below.  I don't spot any obvious problem.  I suspect
something odd is happening when running 'dpkg'.

Any ideas how to debug this further?
