Duplicity throwing an exception on restore and on backup

Applications
1

I recently tried to restore a few files and duplicity threw an exception. From then on, it started throwing an exception when I’m trying to backup. So now I can’t restore, and can’t backup. Here’s the exception:

Traceback (innermost last):
  File "/usr/bin/duplicity", line 92, in <module>

                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^
 KeyError: 1

It happens every time I’m trying to run my backup.

I’m using the distro version of Deja Dup, version 44.0. Here’s the debug information from the app:

Trying to use duplicity directly, I’m getting:

For your second comment (FileNotFoundError: [Errno 2] No such file or directory: '/tmp/duplicity-3p_at5py-tempdir/tmpkqg658l5'), I’m not sure what’s happening there.

Looks like Duplicity couldn’t even make a temporary folder…?

For your first comment, I think I have a suggestion.

Check your target backup folder. You likely have two files in there with the same name but different file extensions (so like duplicity-*-vol1.tar and duplicity-*-vol1.tar.gz or similar).

That error suggests that Duplicity found two volumes with the same number… I would say move both volume files to a separate folder for now and retry, while we’re debugging this.
