Failed solution to upgrade Ubuntu to 12.04

Some time ago, when upgrading from ubuntu 11.10 to 12.04, I don't know if it was because of the network or something suddenly got stuck, and it was still stuck in the same place the next day. Looks like it crashed. Restart to enter ubuntu after forced shutdown, due to update failure, keyboard and mouse can not be used, the resolution is very low. Fortunately, the tab key still works. The network card driver is gone and cannot be updated on the Internet.

The solution is as follows:

1: press the shutdown key and restart using the tab key

2: select the pre-upgrade version of recovery mode in previous version, and then fix it with network.

3: restart, select the first option of ubuntu, after entering the network can be used, and then update the software ok.

Ps: you can do a lot of things in the recovery model, cleaning up the old kernel, freeing up space, and so on.

When something goes wrong with ubuntu, you can enter the previous version or fix mode.
