Being probably too presumptuous I am trying to follow the guide
Nextcloud, your personal cloud server, on Openmediavault
from Techno Dad Life but I got stuck at the editor GNU nano2.7.4 witch give me a page with menu but completely blank after I typed
cd /sharedfolders/AppData/Nextclouddb
nano custom.cnf
subsequently in my nextclouddb folder I am getting a file custom.cnf.save instead of custom.cnf
I am not sure what I am doing wrong
