I'm using Ubuntu 12.10 and update regularly. But the last update completely broke my PC. When I restarted the computer, I just saw an orange-blinking screen. I restarted a few times and nothing changed.
So I reinstalled everything from my USB which has 12.10 version. I checked option "download updates while installing". And after finishing installation I still saw the orange-blinking screen.
I then reinstalled yet again but unchecked "download updates while installing" and now everything went well.
My question is: is this some well known bug or am I the only having such problem? Is there some specific package I should not update? How do I find out which it is?
