Can't install Sub-Zero plugin on Raspbian

Server Version#: 1.18.7.2457

I’m trying to install Sub-Zero subtitles plugin on my Plex Media Server running on a Raspberry Pi (Raspbian OS), but without success.

From several sources I read online, you are supposed to put the “.bundle” file on Plex plugins folder, restart the server, and it should be installed.

However, I’ve tried putting it in:

/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-ins/
/usr/lib/plexmediaserver/Resources/Plug-ins-77cb9455c/

And it has not worked. At least, nothing show up in my Agents nor in Plugins in Plex Web.

The guides I read talk about the “Channels” option, but it is not available for me (maybe it was discontinued?).

Any help is gratefully appreciated.

Please don’t post both here as well as on GitHub
