ubuntu16.04 boot blue screen problem

Today, my ubuntu has a blue screen when booting up, and the restart is not easy, so I have looked for many methods, but some methods are very troublesome at first glance. . . . So I found the easiest one, although it seems a little bit ridiculous. . . But it works really well.

The above method is really easy to use. I use dpkg. It will be very slow for a while. At this time, you can cancel directly by ctrl+c, and it will be fine. . . .
