upgrade from 11.10 desktop to 12.04 failed - need help fixing
 

Hello,

the upgrade from 11.10 desktop 64 to 12.04 failed partway through - got stuck trying to restart mysql server and extracting libc6

now it wont reboot

i am trying to recover via live cd and do a fresh install but i want to transfer some files from the home directory to a second drive

the drives seem to mount via live cd (just trying it haven't installed)
but it wont let me transfer the files to the second data drive due to permissions
also would let me gain ownership of the files

boot drive > 2tb - mounts and folder and files can be viewed / read
data drive 1 > 3tb> was mounted in /media/data1
data drive 2 > 3tb> was mounted in /media/data2

data drive 1 & 2 will mount (seems to be in the same place) but when i click on them they wont let me view folder structure and they dont show up in navigation of drive
it indicates im not owner and cant change permissions

also im not sure how to change mount point / im not sure if they are mounting correctly
as live cd did the mounting

I would appreciate any help..

Thnks

Try using sudo, sudo nautilus or gksudo nautilus in a terminal to access the /media directory from the CD.

failed update to 12.04
 

Not sure this is relevant, since this is an old post. Anyway, I had the same problem. And its not completely resolved yet. I did use the live boot option with a disk and did a reinstall, trying to save my old data. This worked to some extent, as I was able to access the section of the hard drive that had my old data. BUT, like you, I had access issues,as the system reported I was not the owner of some of the files. I used the terminal program with the CHOWN command to switch ownership of the files.

if you use sudo chown You -R Oldspot it should allow you to access the files.
In this example, You (equals your name in Linux), -R recursively fixes the whole dir, and Oldspot means the folder that you want to change ownership from. You should probably read the description of chown in the help file before you do this, but it really worked for me. I used Puppy (yet another version of Linux) to copy the files from one segment of my hard drive to another, then I used chown to enable the owner to change from whatever to me (Bob) in my case. The SUDO makes this a super user command so you can get the rights you need to solve this. I had great success with 12.04 on one computer and some complications on another. However, I still like it. Honestly, my main Linux box uses Linux Mint, and it is very stable so I like it very much. Hope you have solved your issues!
