autopkgtest-build-qemu fails to build Ubuntu images

[Paride Legovini]

Normally autopkgtest-buildvm-ubuntu-cloud is a better tool to build Ubuntu images to be used with autopkgtest-virt-qemu, however we should also be able to use autopkgtest-build-qemu, which builds an image from scratch using debootstrap. This currently fails:

- When building >= Focal images, autopkgtest-virt-qemu fails as it tries to install ifupdown on the testbed, which is not available in main (the only enabled component during debootstrap). We should stop installing ifupdown in >= Focal or more probably >= Bionic (when netplan has been made the default).

- Issues with setup-testbed installing rng-tools have been reported [1].

Note: at the moment autopkgtest-build-qemu is also failing to build noble images because the release pocket is currently missing binaries.

The rng-tools install problem was due to a local configuration issue. Not a bug in autopkgtest

The ifupdown issue has been fixed in:

The MR has been merged but the commit hasn't been released in Ubuntu yet. Version 5.35 in debian has the fix.

I am also affected, cannot build an Noble Ubuntu image on Noble host using the following command:

$ sudo autopkgtest-build-qemu noble noble.img http://fr.archive.ubuntu.com/ubuntu
