Hi there Stuckless / Sean Like you I experienced the same issue after upgrading to 6.5. After a little investigating I found it to be an issue with my hostname. Up until now there have been no issues with my hostname containing an "_" but possibly something has changed with 6.5. Basically i went through to /boot/config/ident.cfg and edited the hostname from "media_server" to simply "mediaserver", rebooted and the issue was no longer. The file update also seems to push through to the core /etc/hostname & /etc/hosts. If this was not your issue... there was also a similar error and resolution in the post below... As for the downgrading when i returned to the update os selection through the GUI i noticed that there was now an option to revert to my previous version, however I am unsure if the same will result with 6.3.5 but its worth checking Good Luck Hopefully you manage to resolve your issue Regards
