Open a terminal and run

Code:

sudo rm /var/lib/apt/lists/partial/* -vf

then run

Code:

sudo apt-get update

and see if you get the same error.

Good Luck

Hi

same command again

Code:

sudo rm /var/lib/apt/lists/partial/* -vrf

Then pick a different server using update manager and then

Code:

sudo apt-get update

Kind regards

Open Software Sources and disable the Precise repositories.

Then run the "rm" command again and then run the "apt-get update" command.

Good Luck
