So im on ubuntu 14.04
Now my roku have updated plex i can no longer access my media
It wont let me update to 1.18.3 or higher
I host my plex and media on a server as i cant house one in student accommodation.
You should note that Ubuntu 14.04 is outside of the standard support by Canonical: https://wiki.ubuntu.com/Releases So unless you are paying for updates, you aren’t even getting security fixes anymore. You really should get to a supported version of Ubuntu.
