Oh, you got a working result? I tried aspcud in various variants, but I
don't get any solutions. https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=897330

Of course the autopkgtest-sat-dep package should have versioned
dependencies and/or on the command-line, versions should be specified
IMO.

  autopkgtest merrily went ahead and removed all of those packages,
  which it turns out breaks package extraction, causing a tmpfail and
  then destroying all workers in turn.
