Multiple head revisions after git pull (2.0rc1 --> 2.0)

Hi,

After my stash & pull to upgrade from 2.0rc1 to 2.0, these commands both
end in the error below.

- ../web$ FLASK_APP=pgAdmin4.py flask db revision
- ../web$ python pgAdmin4.py

File
"/home/wbloos/.virtualenvs/pgadmin4/lib/python3.5/site-packages/alembic/script/revision.py",
line 270, in get_current_head
"%s(at)head" % branch_label if branch_label else "head")
alembic.util.exc.CommandError: Multiple head revisions are present for
given argument 'head'; please specify a specific target revision,
'<branchname>@head' to narrow to a specific head, or 'heads' for all heads

I use Version: webpack 3.6.0

Any tips?

Cheers,
