The essential question is – does it read back true for mono?
I assumed that if I export it as root and duplicati runs as root it would be the same but I don’t know much about environment variable scope.
Thanks, I used systemctl edit duplicati.service
to set the environment variable there as
[Service]
Environment="MONO_URI_DOTNETRELATIVEORABSOLUTE=true"
and it works. I guess this is perfect workaround for now since it is persistent and should not impact anything but duplicati.
