Hello! We have now a PPA for rdiff-backup which has daily development builds based on latest git master. I would be very happy if the Ubuntu/Debian users on this mailing list could participate in the rdiff-backup Python 3 rewrite project on their own behalf by testing out the development versions and filing bugs/debugging/fixing them at https://github.com/rdiff-backup/rdiff-backup to the extent you have Python skills.
Quick install steps: sudo add-apt-repository ppa:rdiff-backup/rdiff-backup-development sudo apt-get update sudo apt-get install rdiff-backup If you encounter bugs, file them at: https://github.com/rdiff-backup/rdiff-backup/issues I am also interested in finding co-maintainers for the packaging and project in Debian/Ubuntu (e.g. https://launchpad.net/rdiff-backup, https://github.com/rdiff-backup/rdiff-backup/issues/55). Let me know if you want to help! - Otto
