Comment 12 for bug 1855736

You're not being difficult, the problem is vexing!

Try this:

    $ PYTHONPATH='.'duplicity/dup_main.py

It should work like this too:

    $ duplicity/dup_main.py

In either case there should be no output. Please log whatever happens. Perhaps there's a missing module or something. Python imports don't tell you a lot when they go wrong.
