Trying to install Plex Media Server with LE v11.0.1 on Wyse 5070 (Pentium Silver J5005), but cannot find PMS by searching the Add-Ons section (the Plex client does appear however), so went to Plex website on another PC to download the Ubuntu (16.04+) / Debian (8+) - Intel/AMD 64-bit PMS version.
Compressed to a zip file and copied to USB stick, went to install using the Install from zip-file option, but receive an invalid structure file error.
No success despite repeating these steps. I have plenty of free memory and the CPU is idling along with no load. What am I doing wrong?
