There is a workaround that fixed the problem for me. It was obviously related to `python-paramiko`.
1. Remove the `python-paramiko` package instelled w/ apt: `apt remove python-paramiko` 2. Install paramiko via pip that provides a newer obviously fixed version: `apt install duplicity python-pip -y` `pip install paramiko` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1665643 Title: Duplicity error "ssh: Unknown exception: CTR mode needs counter parameter, not IV" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/duplicity/+bug/1665643/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
