[Bug 1384706] Re: tar: Unexpected EOF in archive in copyup()

[Martin Pitt]

Indeed I'm aware of it, it occasionally happens on other autopkgtest
runs, too. It's just exceptionally hard to reproduce locally. I already
spent some hours trying to understand and reproduce the problem, so far
not very successfully :-(

  This looks like bug 1317358 but the autopkgtest version used in the
  MAAS lab includes the fix for it, so it might be a new root cause.
