And even though this is lemmy, when I searched for “Ubuntu Help”, there’s no community named that. There’s also no community named “Linux help”. Which I find very very odd. Lemmy of all places you’d think would have a linux help community!
Have you been by !linuxquestions@lemmy.zip yet? Nevertheless, this community should work just as well.
There's also !linux4noobs@programming.dev or a community with the same name on Lemmy World. When specificity in a search fails, falling back to broader/more basic terms may help (e.g. searching for Ubuntu or Linux).
Personally, the childish side of me will always get a kick out of .wtf in a website name.
