Thats pretty much the entire point of this, they stated these are all scene releases. So fitgirl et al etc.
For some masochistic reason they sometimes come rar'd, iso'd, and custom windows based unpacker which is all really unnecessary and creates more points of potential failure for the linux gamer.
LinuzRules releases have linux .sh based unpackers, but even those arent guaranteed to work and can get stuck. I'd much rather just get the complete uncompressed files.
Tl;dr Scene releases use unpackers which often fail and multiple levels of unnecessary compression.
I find Organizrr to be much more comprehensive dashboard. And Lol at running plex just to use overseerr but still streaming with Jelly 😂 just use Jellyseerr, delete plex/over, and save a TON of system resources.
