The solution above fixes the problem for me:
https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/370294/comments/1

For someone not used to command line operations, from the terminal just do:

gksu nautilus (it will ask for your pwd)

Then navigate to /var/lib/apt/lists

Choose: "View" --> "List"
(can also be done via CTRL+2)

....and then click on "Type" in the Nautilus interface in order to get all files of the same kind to line up with each other.

Mark/highlight all the files of the type HTML and delete them. (I actually copied them to another folder just in case they were needed, but they once they are gone all is fine (for me)).

Finally:

sudo aptitude update (or run your usual GUI).
sudo aptitude dist-upgrade
