Update of sonarr not working and ends with error in log

Help & Support
#1

I’m using sonarr including mono 3.10 on my qnap nas. I’m running the master branch version and would like to update to the newly released version now but it doesn’t work. I’ve enabled automatic update through the built-in script but this didn’t update to the new 2.0.0.2500. So after this I tried manually which shows an error in the log

Message
Update process failed: ApplicationName=‘mono’, CommandLine=’/tmp/nzbdrone_update/NzbDrone.Update.exe 5969 /tmp/nzbdrone_update /share/MD0_DATA/.qpkg/NzbDrone/NzbDrone/NzbDrone.exe’, CurrentDirectory=’’, Native error= Cannot find the specified file

Exception

How can I fix this and update to the new version? The version i’m running at the moment is 2.0.0.2341

Not able to update

I did some more searching and it seems the problem is mono is not on the path.

I’ve fixed this on my qnap by adding mono to the path through optware

Run:

ln -s /usr/local/bin/mono /opt/bin

to create a symbolic link to mono using the optware directory.
