If Ubuntu Linux on the desktop was a car
Today when I went out to the garage, two wheels were missing from the car. After some searching it turned out to be a conflict between the mechanic and the guy who changes the wheels to winter tyres. I pinned the mechanic to the ground and praised the tyre guy a 1000 times, and the wheels snapped on again.
A security update (UPS update) had disabled old unsafe driving modes such as driving in reverse. It was just a question of going under the engine hood to file off two serial numbers and I could after a restart, back out of the garage.
The car keeps middle-honking when I turn the steering wheel but there is no workaround as of right now.
