Hello!
I’ve been having some issues with the web panel of MineOS, and have decided to just use screen to run my servers. is there a way to uninstall the web panel (or delete the files that load it), so I can just use the base OS?
Thanks 
Depending on how you installed it, which is likely using supervisord, simply remove the mineos entry in supervisord, then delete /usr/games/minecraft.
(/usr/ not /var!)
