Upgrade interrupted, 10.04 to 11.4, can not boot now.

[Dekkenz]

Hey,

So I have ubuntu 10.04 installed on my laptop, which I use mainly for browsing the net and watching movies.
2 Days ago it prompted an upgrade to version 11.4, I accepted, but while it was upgrading my power died.
Now I can not boot at all.
I keep getting this error:

Kerneal panic - not syncinc: VFS: Unable to mount root fs on unknown-block(0,0)

All I can do is access the command line ( grub ), and a limited root account?
This is what I get when I try to use "sudo apt-get upgrade"

W: Not using locking for read only lock file /var/lib/dpkg/lock
E: dpkg was interrupted, you must manually run `sudo dpkg --configure -a` to correct the problems.

And when I run `sudo dpkg --configure -a` I get:

dpkg: error: unable to access dpkg status area: Read-only file system

Help?:(

Hi and welcome to the forums :-)

I think the best thing to do in this situation is to boot the computer with a LiveCD/USB and see if you can access your important data to save it.

Once that is done, please do the following:

Boot the Ubuntu Live CD/USB. Choose the option "Try Ubuntu without any changes." Once the desktop loads come back here and do the following:

1. Download the boot info script which is in a zipped file. There is a link in my signature.
2. Once downloaded, move the boot info script by either copying or dragging and dropping the zipped folder onto the desktop and unzip the contents by using right-click Extract here.
3. Open the folder and copy the script to the desktop (you can also drag and drop if you like)
4. Open a terminal and run the following command


sudo bash ~/Desktop/boot_info_script.sh

This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here in a new post. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

Hey,

Thanks for the reply.
Here is the output of RESULTS.txt:

Can't I just finish the system update somehow using this LiveCD?

[Rubi1200]

I think there is an option on the CD to repair a broken system and if you have backups of data it might be worthwhile trying it. If not, it might be best to just reinstall.

[Dekkenz]

I have checked the CD, there is no repair option as it seems.

[Rubi1200]

The only other way I know of is to do a chroot from the LiveCD (and you must have an Internet connection for this):



sudo mkdir /mnt/temp
sudo mount /dev/sda1 /mnt/temp
for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt/temp$i; done
sudo cp /etc/resolv.conf /mnt/temp/etc/resolv.conf
sudo chroot /mnt/tempThis will bring you to a root prompt so any commands after this do not need sudo.

I would start with the following:


apt-get autoclean
apt-get clean
apt-get update
apt-get upgrade
apt-get dist-upgrade
apt-get install -f
dpkg --configure -aIf all this completes without errors, reinstall GRUB for good measure:


apt-get purge grub grub-pc grub-common
apt-get install grub-common grub-pc
update-grub

Then finish up:


exit
for i in /dev/pts /dev /proc /sys; do sudo umount /mnt/temp$i ; doneReboot.

I do not seem to have this file:
sudo cp /etc/resolv.conf /mnt/temp/etc/resolv.conf

I have a folder called resolvconf, and that is about it.

Edit:
I get this: "E: Unable to locate package grub-common"

Can you access your data?

I really think you would be better off saving data and reinstalling in this situation. There are too many errors and too many unknown factors to try and fix this effectively.

Clearly something got badly broken during the upgrade attempt and unless someone else has more ideas I would recommend going for a fresh install.

Yea, I created a partition with the old data, and installed ubuntu on the new partition.
I will move all the data I need, and format the old partition, and merge if possible.

Thanks for all the help!
