Cannot Update Ubuntu

[fgerst]

I have not been able to update. When I go to update, I cannot unselect SunJava. SunJava will not reinstall or update; when I go to accept the terms and conditions, I cannot select the box to agree and the package manager crashes. I have repeatedly attempted to completely remove the broken package, but I get an error message saying it could not remove it because it was in such an inconsistent state. Help!

Hit the Tab key to highlight the <OK> and Return key to accept it.

In terminal

sudo apt-get update

If any error

sudo dpkg --configure -a

Now install sun-jre

sudo apt-get install sun-java6-jre

Remember to tick on agree option while installing.
