I installed on my qnap TS-669 Pro x86_64 ubuntu over chroot, Filebot, Oracle java 8u111 64bit.
When I test filebot i got Errors where "GVFS: OK" should be. I think it is not an bug of Filbot but I dont know where to ask.
root@Olymp:/home/Filebot_Test# /home/filebot_music.sh
Locking /home/Logfiles/amc.log
Run script [fn:amc] at [Tue Dec 06 15:18:24 UTC 2016]
Illegal usage: no input
Failure (°_°)
/home/filebot_music.sh: line 23: ut_dir=/home/Filebot_Test: No such file or directory
You can see I'm in the folder "/home/Filebot_Test"
This is clearly a command-line issue that has nothing to do with filebot specifically. The error message hints at ut_dir. The command has one odd commented line just before ut_dir. Take the hint.
Next step is trial and error until you understand intricacies of bash code, i.e. ending a #comment line with \ may not work the way you think it works.
PS: use the sysenv script to see what arguments you're actually passing in
