developer from dev core team, patrick.
im currently lestening from launchpad and heard things about ur issues, im heading u a list for rescuing ur details,
here's the solution,
1. launch the terminal for devmode use,
2. replace the key with unlock status for dev-ops.
3. hid the radiobutton for captitable options until its unlocked
3. replace it with its saying unlock to see the staus (usually requires people to auth the app for the highest administration with password) and auth the gufw for root at all.
finally u'll resolve the problem uve met
best regards Patrick ;)
