p.s. switch to docker

Very helpful, I’ll switch to something not-tt-rss instead.

very much so. by using tt-rss via docker(-compose) you would get an actual stable proven working base for the application, as opposed to your r/unixporn ricer kids distro that you broke somehow and can’t even fathom what happened and why:

see, computers are not humans, they don’t do things randomly. there’s always a cause. you just don’t have the capacity to see it.

i’m entirely unsurprised that you would ignore good advice though, otherwise you’d be using software stack fit for running servers on and we wouldn’t be having this conversation.

that’s not going to fix the underlying problem though, i.e. your technical ineptitude, and bad decisions stemming from it.
