Recently, a new answer popped up for a "resolved" question:

I can't get this to work! I've tried to do it manually and in terminal but nothing works. [...]

(why cant i post comments!?)

Like a good worker bee, I immediately reported it as not an answer, but — as it turns out — the existing answers did not actually work anymore. So I updated the accepted answer.

The problem is: that wayward commenter had no correct way express the inadequacy of existing solutions. They had only 1 reputation point. What should low-rep users do in this situation?
