I got your point about reporting the bug, I just (in general) don’t want to report bugs against old versions. I get that it’s up to me to keep apps updated if I won’t alow nextcloud to do so, but that’s a price I’m willing to pay for not allowing traffic to basically anywhere. (And unlike AWS, github is sufficient different from “basically anywhere”, that I’ll consider allowing traffic to there if it will give me notifications)
I found out that I actually extracted the .tar.gz’s in /var/www/nextcloud not /var/www/nextcloud/apps, when I fixed that things worked.
Thanks for all the help and suggestions, even though it seems to have mostly me doing silly things.
