This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I found a partial answer by myself: But, what about security updates? If the package is blocked, i don't have security updates for currently version. – Alessio Mar 14 '12 at 12:05

Yes but you will need synaptic installed

sudo apt-get install synaptic

Then open synaptic and search for the package you want to lock and go 'Package>Lock Version'

As far as i can see this will solve your problem. – edm Mar 14 '12 at 13:27

Try this:

Update Manager > setting (software sources directly from Dash) > updates

and then check just the security updates, the other updates will be manual.
