[Duplicity-talk] Error with B2 - TypeError: argument should be a str object or an os.PathLike object returning str, not <class 'bytes'>

[Paul Galbraith]

I've been using duplicity for a about a year on OpenBSD but now I am 
getting an error apparently when duplicity is trying to get signatures.  
I suspect a recent OpenBSD upgrade is part of the problem, python was 
upgraded 3.9 -> 3.10 and many python dependencies are updated.  I've 
tried re-installing duplicity and dependencies, but haven't had any 
improvement after doing so.  If anyone can point me in the right 
direction I'd be very appreciative!  This is the tail of the output from 
duplicity:
