This edit was rejected(huh?), can someone approve it? Submitter is an Ubuntu Core Dev and is a fix (installing linux-generic instead of linux-image)
An already rejected edit can't be rolled back nor undo:
There is no undo at the moment, I always planned to have undo gmail style. But we have resisted complexity here. Once you have undo, you have to add a slew of checks prior to undoing.
On SO the community will pick up and approve if you just made a mistake. On other sites, you can go and manually apply the edit if this was an honest mistake.
I've just applied manually the edit.
