For reference, upgrading this to Python 3 should be simple. sshuttle works fine with Python <= 3.7.
BUT: sshuttle is currently incompatible with Python 3.8. See https://github.com/sshuttle/sshuttle/issues/381 Help fixing this appreciated. I don't have a lot of time right now, and this looks like it could be non-trivial to fix. -- Brian May <b...@debian.org>
