Bug ID: 40217
           Summary: Ubuntu vivid / wily use libgnutls 28 instead of 26
           Product: Packaging
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wine-packages
          Assignee: [e-mail]
          Reporter: [e-mail]

      Distribution: Ubuntu

The Ubuntu builds use the correct build dependencies for libgnutls but the
"Recommends" entry is wrong:

{{ ="      libgnutls-deb0-28,\n"                if debian_version >= 8 else ""
}}
{{ ="      libgnutls26,\n"                      if debian_version < 8 else ""
}}

Ubuntu vivid/wily also use libgnutls 28, so we need to change this construct to
be compatible with launchpad and recommend the correct version.
