[Bug 2000015] [NEW] autopkgtest unshare-qemuwrapper doesn't build chroot with sbuild/lunar-proposed

[Mauricio Faria de Oliveira]

Public bug reported:

The autopkgtest `d/t/unshare` uses `sbuild`, which fails on lunar
(sbuild 0.83.1ubuntu1) as the chroot setup cannot find `adduser`
(not in the chroot as it's now an alternative dependency in `apt`).

This is fixed in lunar-proposed (sbuild 0.84.1ubuntu2; commit [1])
since it no longer depends on `adduser` in the chroot.

https://salsa.debian.org/debian/sbuild/-/commit/0d35fa019a5c6d51e0928987a87849766b0f35e6

However, `d/t/unshare-qemuwrapper` runs `d/t/unshare` in a qemu vm,
but its image still does _not_ ship `sbuild` from lunar-proposed, 
thus `unshare` fails anyway (and its parent `unshare-qemuwrapper`).

The reason is, even though the apt _sources_ are used to build the
vm disk image thus `lunar-proposed` is _available_, it is not used
because the apt _preferences_ (w/ `autopkgtest --apt-pocket` setup)
are not copied in.

This is now required as lunar has -proposed pocket w/ NotAutomatic.

Just checking for/copying the apt preferences file/dir address it:
+ mmdebstrap ... --setup-hook=sync-in /etc/apt/preferences.d/ ...


Tests:
=====

$ autopkgtest-buildvm-ubuntu-cloud -a amd64 -r lunar

Title:
  autopkgtest unshare-qemuwrapper doesn't build chroot with
  sbuild/lunar-proposed

Bug description:
  The autopkgtest `d/t/unshare` uses `sbuild`, which fails on lunar
  (sbuild 0.83.1ubuntu1) as the chroot setup cannot find `adduser`

  This is fixed in lunar-proposed (sbuild 0.84.1ubuntu2; commit [1])
