Package: duplicity
Version: 0.8.04-2
Severity: normal
Dear Maintainer,
I am attempting to use the new python3 version of duplicity for Backblaze.
Note: I have installed the python3 b2 library (pip3 install b2).
Any use fails with:
Attempt 1 failed. TypeError: can only concatenate str (not "bytes") to str
Using duplicity -v9, we can see that the error is in b2backend (not in the b2
library):
File "/usr/lib/python3/dist-packages/duplicity/backends/b2backend.py", line
121, in _put
log.Log(u"Put: %s -> %s" % (source_path.name, self.path + remote_filename),
log.INFO)
TypeError: can only concatenate str (not "bytes") to str
Adding some debugging code I can see that the type of self.path is <class 'str'>
and the type of remote_filename is <class 'bytes'>.
Here is the full -v9 output (with my account number replaced with X's):
