"Bad File Descriptor" when Indigo can't write to directory because of permissions #415

Closed ckuethe closed 2 years ago

ckuethe commented 2 years ago

Is "Bad File Descriptor" the right error? indigo (uid=1001 on this machine) clearly doesn't have permission to write to /root (uid=0). I didn't check to see what happens if I try to write to a nonexistent server path, eg. /home/indigo/images/2021-11-13/orion_nebula
