Yes AES. For me it sounds like a regression introduced with 2.0.5.110 as it was working fine with one of the previous releases (I think the last successful backup was with v2.0.5.108-2.0.5.108_canary_2020-07-09).
Maybe it was introduced with the following change in the Release v2.0.5.109-2.0.5.109_canary_2020-08-07 · duplicati/duplicati · GitHub release?
- Updated to use and require .Net 4.7.1, thanks @warwickmm
I’m running duplicati as a service on osx and updated using the internal updater. I’ll try ot do a clean re-install (I just have to figure out how I managed to get it running as a service in the first place :))
I got it working again after
- manually installing the latest .dmg (not sure if that was necessary)
- updating my mono version using brew (as described here MacOS / OSX service installation)
