I have just installed a new KDE-based system and wanted to add a printer, but it gave me error “Failed to get a list of devices: Forbidden”. Cups is installed, I also tried entering the root password but I couldn’t add a printer.
Adding myself to the sys group finally solved the issue.
I was wondering if this is something other KDE users have experienced? Maybe something that needs to be fixed in cnchi, or something I may have caused myself?
