My pgAdmin is broken

A couple of days ago I tried upgrading to v3.0. This never worked for me.
Normally I activate the python environment and then install the latest
wheel file to upgrade. I was never able to login successfully on v3.0.

So I gave up and tried to go back to v2.1, again I did so by reinstalling
the v2.1 wheel file. However afterwards I can't launch pgAdmin. I get this
error message:

alembic.util.exc.CommandError: Can't locate revision identified by
'50aad68f99c2'

I've now burned several hours on trying to fix this. What is the best way
to at least get back to a working system with v2.1? In the future is there
some better way to upgrade or revert to a previous version when things go
wrong?

Thanks, Derek
