Plex won't start on Libreelec 11 due to Python 3.11 deprecating inspect.getargspec()

ExpiredKebab · March 7, 2023 at 1:28 AM

Hi all,

I just upgraded Libreelec from 10.0.4 to 11.0.0 on my RPi4. I'm having trouble starting Plex on it now. It hangs at the startup screen with 3 dots (like pending).

Attaching the Kodi log file.

Searching around inspect.getargspec(). This function seems to be deprecated in Python 3.0. It seems to be still available in 3.10, but not in 3.11. Didn't find much about selectedServer though.

Not sure how to go forward from here. Appreciate any advice.

Ta.

The official Plex add-on is broken and needs to be fixed by Plex devs.

Until that happens I've been using the version here: https://pannal.github.io/dontpanickodi/ which works fine. There are quite a few refs to it in the Plex forums.

Thanks! Good to know.

I'll give the Plex forum a nudge, and also take a look at that GitHub link too.
