udenadm trigger is not permitted while ndev is unconfigured

[apachemaven]

HI:
Last night, when I update the ubuntu, I set it shutdown after 60 minutes uisng "sudo shutdown 60",because I think the update will complete in 40 minute.
However today when I start the computer, it can not startup the ubuntu.
I got a screen which sown the message in the title,after I search it using google, some people have encounted this proble, their solve way is to use a live cd to chroot to the old root and complete the update.
However I can not.
The following is my suitation:

http://imagebin.org/87841 my command


http://imagebin.org/87840 my partition

SO, how to do now? I am in hurry, I hope some one can do me a favor.
Thanks.

Not sure why you stopped. If you notice in your first screenshot, after the 'chroot' command, you're apparently in the root directory (/) after being in home (~). This means the chroot was successful, despite a few errors. The mounts you've created were all successful.

Keep going.
