Thanks, not solved yet, but we're close. Below is the current output. The call actually goes through to the server. BUT, where the asterisks are is the Base64 encoded password... and it has a leading " b' ", which my working duplicity install does NOT have. I am not sure if that is a part of the newly created byte array, are that it gets added somewhere else when the byte array is printed.

Actually, it looks like this solves this error, thanks to https://stackoverflow.com/questions/31144988/base64-encodestring-failing-in-python-3.

Change line 291 to:

 return u'Basic %s' % base64.encodestring(auth_string.encode()).decode().strip()

Now a backup starts, and we hit the next error once the first volume is uploaded:

Any ideas? :-)
