Package Error

[snav3]

Hi, I have been having a hard time with my Ubuntu OS it's been giving me an error in the system but as it tries to make an error report it fails the reason being it can't identify the packet id.
Here the example of the error i've been getting while trying to update or install packages,
when using the terminal
sudo apt-get install f-
or
sudo apt-get install 3kb
<this is what it gives>

'E: Encountered a section with no Package: header
E: Problem with MergList/var/lib/apt/lib/apt/list/extras.ubuntu.com_ubuntu_dists_natty_main_i18_Tran slation-en
E: The package lists or status file could not be parsed or opened.'

Tried the Update manager within the Ubuntu OS but as it loads it gave me the same error report but this time stating I should report this to the 'update-manager'

Please do advise,Evans. :confused:
