Thank you for your bug report, some questions - what version of Ubuntu are you using - why is gnome-keyring not installed? - could you get a backtrace (https://wiki.ubuntu.com/Bugs/Responses#Missing_a_back_trace)
It looks a bit like https://bugzilla.gnome.org/show_bug.cgi?id=785674 which was fixed in 1.8.12 (so should be fixed in cosmic but not in bionic) ** Bug watch added: GNOME Bug Tracker #785674 https://bugzilla.gnome.org/show_bug.cgi?id=785674 ** Changed in: network-manager-applet (Ubuntu) Importance: Undecided => Low ** Changed in: network-manager-applet (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1806269 Title: nm-connection-editor crashes when trying to modify connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1806269/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
