And, by the way, and I don’t mean this specifically for the OP, but rather for everyone who seems to think we’re their personal entertainers. if you just need a few examples, AI is actually perfect for that. I mean that seriously.
Or you could just google “how to use the Nextcloud occ command,” and you’ll instantly get hundreds of examples right in your browser.
I don’t want to sound elitist, but if someone would rather write two long stories in a support forum than simply mention what OS they’re using and how they installed Nextcloud, then a lack of time clearly isn’t the issue. In that same amount of time, they could’ve just filled out the support template, at least as much as possible without the occ output, obviously.
