Alright, I'm re-updating to 6.8.0 to get the exact error. Looks like the error is:
Seeing "/dev/dvb" reminds me I had to use a plugin UnraidDVB to get my antenna to work. That might be my issue.
I just updated to 6.8.0 and now my plex wont start. Worked fine beforew my update. Every time I try to start I get a message "Execution Error, Server Error".
I rolled back to 6.7.2 and it started working again. Is this a known issue? Can I do something to fix it? Will it be fixed in an update? Do you want a system log to help understand my issue?
