Bug#1058579: Acknowledgement (apt: gives misleading error when not finding Packages.xz in Release (not InRelease))

After more testing, it appears that the behavior is different depending on
the way the flat repository is used:

* sources.list with ".../deb-amd64/ ci/" (needs "Filename: ci/foo.deb" in Packages)
  => on "Packages" is checked, "Packages.xz" is ignored as previously described

* sources.list with ".../deb-amd64/ci/ ./" (needs "Filename: ./foo.deb" in Packages)
  => a long list of compressed formats is used

I'm a bit unsure whether this would be expected.

Anyway (assuming this is expected), the part of the error message mentioning "Packages"
name may in fact not be wrong per se, but in this (legacy?) use case it could possibly 
be noted that it has to be uncompressed (since "Packages" is otherwise also AFACT used 
to encompass compressed versions as well).

Best regards,
