Changed connection editor to nm-connection-editor from network-manager-gnome
check if nm-tray open nm-connection-editor instead of nmtui
Fairly nitpicky, but your modifications to the patch completely change the purpose. That's fine, but you can now just modify existing information Description, Author, and Bug instead of adding your own lines. Also, please modify Bug to say Bug-Ubuntu, which follows DEP-3.
Otherwise, LGTM. Thanks!
