Does unRAID support running a standard Linux Desktop environment? AFAIK, unRAID just gives you a WebUI and then everything else runs in VMs or docker containers, no?
Are you running FileBot inside a docker container with container-specific minimal Desktop environment?
What would your custom trash command or "manual delete" command be?
Move to Trash will probably just delete the file, or maybe fail with an error message, when the underlying platform does not have a trash or recycle bin, i.e. it'll probably only work on typical Desktop platforms, Windows, macOS, and standard Desktop Linux.
FileBot uses the
Desktop::moveToTrash Java API so the implementation details are platform-dependent. I'm not sure how trash / recycle bin works on Desktop Linux, especially not unRAID. I know that Synology and QNAP do their own thing and don't follow the
XDG standard, so I would assume that unRAID does its own thing as well.
EDIT:
I checked the code and
Move to Trash will just do nothing if it doesn't work, and silently print an error message to the log.
What does the log say?
