Your report got truncated somehow... I need the traceback as well as the error message.

I think this has been fixed in a later version, we're at 0.8.17 now. Please try an upgrade if possible

There are multiple options both stable and daily:
- Source - https://gitlab.com/duplicity/duplicity
- Stable tarball install - https://launchpad.net/duplicity/+download
- Stable duplicity PPA - https://code.launchpad.net/~duplicity-team/+archive/ubuntu/duplicity-release-git
- Daily duplicity PPA - https://code.launchpad.net/~duplicity-team/+archive/ubuntu/duplicity-develop-git
- Stable snap builds - “sudo snap install duplicity —classic"
- Latest snap builds - “sudo snap install duplicity —classic —edge"
- Stable pip3 builds - “sudo pip3 install duplicity"
- Latest pip3 builds - “sudo pip3 install --pre duplicity"

Note 1: UNINSTALL duplicity first if it was installed from a different source..  This is due to divergent install locations, especially between repository installs and the other forms.

Note 2: Launchpad PPAs contain builds for Bionic 18.04, Eoan 19.10, Focal 20.04, and Hirsute 20.10.  Xenial 16.04 works with Snap and Pip installs, but cannot be built under Launchpad PPAs at the moment.

resolved by upgrading to version 0.8.17

thanks Kenneth.

I ran into the same issue, but upgrading to 0.8.19 didn't fix it.

I've put in a new bug for this: https://bugs.launchpad.net/ubuntu/+source/duplicity/+bug/1930640
