Long time ago I install plex media server on a virtual machine Ubuntu 24.04.2 LTS. Its been working great for years but recently (last 2 plex versions updates) when I run the command to update ubuntu, it does not update plex. I check the plexmediaserver.list.distupgrade and its has the right information. The web page tell me there is an update available but it will not install, how could i fix it?
