I installed a fresh Kubuntu-20.04, and created the first user(jacky) by means of the installer of Kubuntu, then I created the second user(leon), by using cmd-line tool "
adduser", and adding it into the group "
root" and "
Both of these two users can login KDE and do things normally, but only jacky can setup printers of the system. When I login with
leon and open "
System Setting ->
Printers", and click the button "Click here to add a new printer", I always get a error msg:
Failed to get a list of devices: 'Forbidden'
in a poped-up dialog box "Add a New Printer".
If with the user
jacky do so, no error occurs.
I guess these two users are different, but I don't know what difference is there and how fix it. Any hints?
