I was using Ubuntu 11.04 and upgrading to 11.10. While the installation process was going on I shut it down. It can't come on again by itself. It will end up showing the status line "checking battery status".

The same problem is mentioned in Crash after update to 11.10, from 11.04 I have tried all my possibilities and all the commands I found in these discussion groups.

The next possible solution is to newly install the OS, but I need the data on my hard disk. As I have made them protected when opened with a LiveCD, there is an error saying "You do not have the permission to access them."

So I need to delete the administrator status through the terminal window. I can access my terminal window and run the sudo commands.

So help me to delete the administrator status through the commands in the terminal window, please.

When you say your data is "protected", do you mean you encrypted your home folder when you first installed Ubuntu (before upgrading)? – Christopher Kyle Horton Nov 18 '11 at 6:35

While in the liveCD, run the command gksu nautilus. This should work as it opens nautilus as root. Alternatively, you can try to copy or move your files using the sudo cpor sudo mv respectively.

Although I thoroughly recommend to copy your data elsewhere, I'm also pretty sure that (if you have /home on a separate partition) you can reinstall Ubuntu without formatting /home.

The error you just mentioned made me struggle for long, and solution is simple. Check this question: Lightdm : Checking battery state - No login screen

EDIT I will quote it for you:

This was not the problem. After reading the log in /var/logs/lightdm I found the problem is .Xauthority was in /var/lib/lightdm/ was owned by root. Deleting it and rebooting the machine did it! Happy with Lightdm!

I had problem of my box failing to start and it ended at "checking battery status" and it will check forever. So I dug and come with solution (I don't remember where I got it) which was to delete.Xauthority file located in /var/lib/lightdm/ – Stefano Mtangoo Nov 19 '11 at 10:11
