[SOLVED] upgrade Kubuntu to 9.04 from 8.10

[sandro54]

Hi guys,
I performed the upgrading to 9.04 by the "apt-get update + apt-get upgrade": the downloading phase has gone ok; during the replacing phase (after about 15-20' ) the procedure ended without any message and returned at Linux prompt (strange).
I restarted the system and at the boot I had the following screen:
----------------
Boot from (hd0,1) ext3 c90ce782 ........etc..etc
Starting up
Loading, please wait ........
Gave up waiting for root device
....
...
etc...etc
ALERT ! /dev/disk/by-uuid/c90ce787-....etc..etc.. does not exist
BusyBox V1.10.2 (....) built-in shell
(intramfs)
-----------------
please how could I exit from this situation ?

Hi, when you boot, do you see the older entry to boot? (older kernel from 8.10). Does that one work? It seems like the root device is not properly set up in grub ...

Yes, I agree with lmilano. At the boot screen, what options are you given: 8.10 or 9.04 or both?

Probably, the solution is just to run grub-install again.
If you can't get into the system at all, boot from any Kubuntu disk, live or alternate and choose the rescue mode instead of live or install. In rescue, you still need to select language, keyboard, region, and then select partition to mount as / partition (if you have encrypted partitions you have a chance to input their passwords).
Give the correct partition, such as /dev/sda1 or whatever for your root partition, where the /boot/grub/menu.lst is installed. Then you can execute a / shell. If your /boot is on its own partition, you will need to mount it first.
If /boot is on your / partiton, then run

grub-install hd0

exit and reboot, it should be fixed.

I solved from the grub using an older kernel and after I have restarted the upgrading to 9.04. It has gone well.

thanks to everybody
