What on earth LLM are you using and do you tell it which distro/version of Linux they are supposed to be working with + give them access to web search or man pages? I haven't had this issue in like a year and a half.
By default I use Leo, and I do specify the distro. I tried to qualify by version, but when I do that I lose out on a lot of correct information for things that haven't changed in awhile.
