For a long time I have been using Sabnzbd 4.12 on freenas. This was running very well. After the indication that 5.0+ is out I tried to update using the script.
You can find the script on http://sourceforge.net/apps/phpbb/fr...&hilit=sabnzbd.
The advantage is that almost everything is installed automatically. But during th einstall I do receive an error message.

Please find below the output of the script when ran in putty.

As I am a newbe in this I do not know how to solve it. I do not want to loose my freenas config as I have all my pictures stored on the raid5 disk.
Would be nice if someone is able to guide me in the right direction.
