I'm also seeing this error pop up in the last few days, despite not making any changes to the backup configuration (using deja-dup).

Thanks Kenneth for the suggestion above about running with the -v9 command.

Is there a way that I could see the exact duplicity backup command that's triggered by deja-dup? (I'm new to duplicity & deja-dup). Thanks!

Here's my system details:

And the error message:
