Trying to upload 'ntfy' returned a weird error:

jas@frallan:~/dpkg/ntfy$ git-debpush
git-debpush: checking state at git@salsa.debian.org:go-team/packages/ntfy.git
-e: fel: v2.11.0-2 är inte en giltig version
jas@frallan:~/dpkg/ntfy$

(I suppose the English text would be something like: '-e: error:
v2.11.0-2 is not a valid version')

For some reason this repository had some debian/v* tags, and removing
them (locally) and then running git-debpush makes everything work:

jas@frallan:~/dpkg/ntfy$ git tag -d debian/v2.11.0-1
Tog bort tagg ”debian/v2.11.0-1” (var 0e3c87e7)
jas@frallan:~/dpkg/ntfy$ git tag -d debian/v2.11.0-2
Tog bort tagg ”debian/v2.11.0-2” (var 37ad0d0e)

For reference, at this point the local checkout had the following

    Bump
jas@frallan:~/dpkg/ntfy$

I think the error message should have been something else then just
'-e'.  Otto's commit related to this suggests he discovered this too,
but I'm not sure if there is a bug report about it.

    Remove 'v' prefix from Debian tags

    Don't add an extra 'v' to tags as it violates DEP-14 guidance and breaks
    tools like git-buildpackage and git-debpush from reasoning correctly about
    what the tags are.

    In practice this will make:
    - debian/v2.11.0-2 -> debian/2.11.0-2
    - upstream/2.11.0 -> upstream/2.11.0

    Only the upstream tag can or should have 'v' in it, but it is currently
    not defined at all in gbp.conf as the field upstream-vcs-tag is missing.
