I just loaded ubuntu 9.10 on my laptop. Toshiba it loaded fine. So I ran update on the system and it updated to teh 9.20 kernel (dont remember act numbers)

But now it wont reboot.

I get udevadm trigger is not permitted while udev is inconfigured
udev settle is not permitted while udev is unconfigured
svgalib: Cannot open /dev/mem
Gave up waiting for root device. Common problems:
-Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait long enought for device?)
- Missing modules (cat /proc modules; ls /dev)
ALERT! /dev/disk/by-uuid/e1768deb-95e0-44bd-96b0-b725c73d42af does nto exist. Dropping to a shell

Busy box v.1.13.3 (Ubuntu 1:1.1.13.3-1ubuntu7) built in shell (ash)
Enter help for a list of built-in commands
(initranfs)

edit:

Kernel 2.6.31-20-generic.

It had
kernel 2.6.31-14-generic

I was able to boot back into the old kernel.. so whats happening? why wont the upgraded kernel work?

This sounds kinda like when I was changing my partition around, I had to do a gnome-update so that it found my drives again. Can't remember the command, I'll go look through where I posted my problem and see if I can't find the command.

By no means am I sure this is your problem though. Just what I think. Sorry I can't be of more help.

cool if you get the command let me know. Im at a loss.

I am not sure this will help, but you can check your fstab settings in /etc/fstab and be sure your computer is pointing to the right place.

ive read somewhere that sometimes ubuntu will prompt the user to reboot before it is finished configuring the packages, the initramfs being one of them

this is happened to me before and here is how i fixed it

try picking maintenance mode from an older kernel in the grub menu and if you get in, chose root shell with networking


if that works run apt-get update
then apt-get upgrade, it might complain and give you a command to run, follow whatever directions you are given

after that run apt-get update/upgrade/dist-upgrade until it says 0 packages to upgrade/install then reboot and see if that fixes it

the short story is you have to force it to finish the update

OK ill give this a try when I get home to the system.

sudo update-grub did not do much.

so i ran these commands and it told me the file did not exist.

file /dev/disk/by-uuid/e1768deb-95e0-44bd-96b0-b725c73d42af

I ran the update command and it told me there was an issue some of the openoffice sw and some other stuff.

sudo apt-get reinstall linux-image-2.6.31-20-generic gave an error..

The process told me to run this command....
sudo dpkg --configure -a

Once I did that I ran the update kernel command listed above and it said not needed or some such message.

I rebooted and things are working now.

So the problem looks like it was with openoffice and some java sw.
Sorry i dont have the actual errors I did not think to save them before the reboot.

Hope this helps someone else if they run into it.

so i had this issue again on another system. the system was not updated and was working fine then it locked up and the monitor went bonkers.

Now i get this

apt-get --reinstall linux-image-2.6.31-20-generic
E: Invalid operation linux-image-2.6.31-20-generic

I guess I should reopen this or open a new issue ...

apt-get install --reinstall linux-image-2.6.31-20-generic

this works now to see if it resolves my issue
