12.04 Upgrade Issue

[Ebonhawke]

Upgraded my desktop from 10.04 to 12.04 tonight (Linux only computer). Upgrade process didn't show any error messages (although last screen was gibberish - just clicked on what looked like 'OK', and it completed)

When I restarted the computer, I got a purple 10.04 screen saying that / drive hadn't been mounted, and 'Continue, S to skip mounting, M for manual'

Thoughts?

If I just 'continue', the computer sits there, with 'skip', it gives an error message (sorry, don't have a screen capture), and M sends me to a terminal window

(Tried sudo apt-get -f install, sudo apt-get upgrade etc. gave me warnings and errors)

To clarify

When I try to boot the machine with 12.04, I get a purple screen with four white dots and the message

"The disk drive for / is not ready or not present"

When I press 'M' for Manual Recovery, and try sudo apt-get update, I get

W: Not using locking for read only lock file /var/lib/dpkg/lock
E: Unable to write to /var/cache/apt
E: The package lists or status file could not be parsed or opened.

After doing a search on Google, found a similar issue

The fix for that was

mount -n-o remount,rw /
dpkg --configure-a

Tried that, and seemed to at least do 'something', however it aborted because of too many errors. I tried apt-get update/upgrade etc, but no dice.

Also, tried looking at reinstalling 9.04 from LiveCD, but it's not loading the language selection screen, so won't let me continue onwards

When I do the apt-get install -f, I get a series of error messages that look similar to:

http://us.archive.ubuntu.com precise replease.gpg
Could not resolve 'us.archive.ubuntu.com'

That prob means no network connection..

During boot process the filesystem is first mounted read only until some point & is then remounted..

Was your 10.04 fully updated before attempting upgrade to 12.04LTS?
Around 10.04 there were problems/changes with grub & then changes to using UUID partition labels..
Some people may have never resolved these..

sudo blkid -o full -s UUID
(lets you see the device & UUID of each partition)

But your problem seems to be with plymouth (greeter) handing over to X server.

dmesg | tail -n 20

Higher Risk:
sudo update-grub

When I ran the upgrade, there were a couple of updates on 10.04 that hadn't been run, but it had only been about two weeks since I last run Synaptic, so I just went ahead and ran the upgrade - perhaps I should have updated first.

Again, through the power of google, the 'could not resolve' issue may be related to losing the dynamic address of the servers.

no DNS resolution could be no network or just badly configured..

run:
dmesg
& read thru for network stuff..(don't post all of it..

What about:
sudo blkid -o full -s UUID
(do the partitions seem as expected?)

Getting a bit frustrated - downloaded the 12.04 iso to create a new USB boot drive (online using a 9.10 boot USB now). Created a boot drive on another USB drive, but when I try to boot from that USB drive, get "Unknown keyword in configuration file", and then the computer hangs.

From the 9.10 boot drive, can see my HDD, and can mount it from home folder on USB drive, but just not sure where to go from here?

As mentioned above, can't seem to reinstall 9.10 on my HDD, can't seem to create a boot disk with 12.04, and can't seem to get rid of the purple screen with "The disk drive for / is not ready or not present"

Output from sudo blkid -o full -s UUID

/dev/loop1: UUID="79fce625-9f86-409c-87cc-d577e60fbf37"
/dev/sda1: UUID="db561c24-c3f8-4047-848e-66012ccb5db9"

/dev/sdb1: UUID="4069-F0BE"

(sdb1 is the USB boot drive)
