This patch solves three issues with Debian packaging / apt: o When building 'testing' only default apt sources is included - backports, updates and security are skipped because they do not exists. o The default release for Debian was `unstable`: this is now fixed to `stable`. o Starting a Debian Stretch VM that was build with diskimage-builder does not work, because some mandatory packages are missing. This patch fixes this problem: it adds the mandatory packages and the test case. Change-Id: If49b5b162c4da1e074e9b19324839bc59d87dc57 Signed-off-by: Andreas Florath <andreas@florath.net>
