I tried to update my Ubuntu software and Java through update manager. However, after all about few hours, it does not have any progress also.

The errors message shown

Software updates correct errors, eliminate security vulnerabilities and provide new features.

I did try to update and upgrade it through terminal but this is the error that I get:

Try it again. sudo apt-get update && sudo apt-get upgrade. If it still errors, change the mirror using software-sources-gtk. – jokerdino Nov 5 '12 at 5:39
