Problems with URL Resolver with Kodi 17 RC3
When certain source links are selected, get the error source not found
This problem is only with Linux distribution – does not show up on Windows of same revision.
The problem is affirmatively resolved (no pun intended) by rolling back the script.module.requests back to 12.9.1
So there appears to be some compatibility issue with the latest version of that module in the Linux system.
Not sure if this has changed in RC4 or final release – still waiting for those to be released in the linux ppa’s.
