 but the switch to more secure repositories is in the works (including usage of https). 
 

Maybe someone can help me set up my server to more secure https. I don't know how.

But really I´ll say it again. These are Problems of only a single or small group of users. If these users have Problems with Repos that can't be deleted than switch to OSMC this is fully configurable And maybe a better solution to them, instead of moaning.  We should try to help making Libreelec 9 better and find bugs so Milhouse can fix them. He is doing an incredible Job and all for nothing, more or less.
