Comment 5 for bug 1859036

At this point you probably have multiple copies of duplicity installed with differing versions.

Do the commands and you should see:

$ find /usr -type f -name 'duplicity'
/usr/bin/duplicity

$ find /usr -type d -name 'duplicity*'
/usr/lib/python3/dist-packages/duplicity-0.8.09.egg-info
/usr/lib/python3/dist-packages/duplicity
/usr/share/doc/duplicity

If you see more than this, remove all of them manually, rerun to check, then reinstall using something other than pip.

There are four options:

* Release tarball install - https://launchpad.net/duplicity/+download
* Daily duplicity builds - https://launchpad.net/~duplicity-team/+archive/ubuntu/daily-dev-trunk
* Stable snap builds - “sudo snap install duplicity —classic"
* Latest snap builds - “sudo snap install duplicity —classic —edge"
