[SOLVED] Failed to create cache dir (linux/transmission)

[liabilityman]

Running transmission on Ubuntu 12.04 server. Just installed filebot v4.0. Followed this guide: http://www.filebot.net/forums/viewtopic ... 1561#p3380 for setting up transmission postprocess script.

Finally managed to get the script running however it seems to fail at creating the cache files. My guess is because the script is being called by the transmission-deamon user which does not have a home directory. I get no such error when running directly from the command line under my own user account.

I assume the default cache location is /home/<username>/.filebot/cache/0 but because that doesn't exist for the transmission-daemon user, it just tries to access /.filebot/cache/0 which is just wrong.

How can I tell filebot to use a different cache location? Or is there a better way to fix this?

Thanks

$HOME needs to be defined, and it normally is in any reasonable Linux distro / bash instance.

Thanks rednoah. I managed to fix this by giving the debian-transmission user a real home directory, located at /var/lib/transmission-daemon
Here are the steps for anyone else who encounters this (which im surprised isn't more people as I have a standard transmission installation).

First stop the transmission-daemon:

Code: Select all

service transmission-daemon stop

Then I set the home location of the user to a place that actually exists:

Code: Select all

usermod debian-transmission -d /var/lib/transmission-daemon

I then ensured the user could write to the directory:

Code: Select all

chown debian-transmission /var/lib/transmission-daemon

Then restart the deamon and now my filebot script works!
