The current behaviour is to modify system connections by default. You either need to be in the admin group, or you need to uncheck the box and create personal network connections. The current behaviour is as intended.
I am marking this bug as "Opinion" since there is a disagreement on whether or not a non-admin user can create system connections. ** Changed in: network-manager (Ubuntu) Status: Confirmed => Opinion -- 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/964705 Title: System policy prevents modification of network settings for all users Status in NetworkManager: Confirmed Status in “network-manager” package in Ubuntu: Opinion Status in “network-manager” package in Debian: Fix Released Status in “network-manager” package in openSUSE: Fix Released Bug description: This seems like a regression?
