Thank you for taking the time to report this bug and helping to make Ubuntu better. I marked this bug as duplicate of bug #964705. Could you please take some time to open one more bug for the udev rule you added? ** This bug has been marked a duplicate of bug 964705 System policy prevents modification of network settings for all users -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1650792 Title: Ubuntu 16.04.1 System policy prevents modification of network settings for all users Status in modemmanager package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: Same bug as described for Ubuntu 15.04 (see https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/964705) is still in my Ubuntu 16.04.1! My workaround is simple but strange: After switching on my notebook, booting into Ubuntu 16.04.1, and being at the login screen, before having logged into any user, the SIM-PIN menu appears. I key in the SIM-PIN, hit the <Unlock> button, then I am asked again for the SIM-PIN, this time with the error message "PolicyKit authorization failed: challenge needed for org.freedesktop.ModemManager1.Device.Control". My workaround: Hit the <Cancel> button After that, I am able to log in and connect with my Aldi/Medion Huawei E173 USB stick to the network, if I am an AdminUser. For a user without Admin-rights it is a little bit more complicated after having logged in: he has to unlock the SIM pin again, then he is asked for the Admin passwort because necessary administrative rights. He has to hit <Cancel> twice, but then he can connect to the network without any knowledge of the Admin-paswort. Strange! Will Ubuntu 16.04 sometime come to the point of enabling mobile networking as simple as it was with Ubuntu 14.04?
