Package: perl-modules-5.22
Version: 5.22.1-3
Severity: important
Currently, perl-modules-5.22 has an unversioned Provides/Breaks/Replaces
against perl-modules. I assume there are two things you're attempting
to accomplish with this:
1) Force a smooth upgrade from perl-modules to perl-modules-5.22.
2) Allow for a perl-modules virtual package to exist with future
versioned perl-modules-X.XX packages.
In both cases, that Breaks should be a Conflicts.
1) The "hint" for complete replacement of A with B for high level
dpkg frontends is an unversioned Conflicts/Replaces pair.
2) Virtual packages are defined as a Provides, or Provides/Conflicts
if they shouldn't be installed together, or Provides/Conflicts
and Replaces if they have file overlaps.
A good rule of thumb is that if you have a versioned Conflicts, you
probably wanted a Breaks, and if you have an unversioned Breaks, you
probably wanted a Conflicts.
