Hello, This didn't solve the problem, unfortunately. There must be other packages that prevent the upgrade, which I can't find due to my poor level knowledge. I must have installed something once, but what ? So, as this case is set as closed or so, I think the best I have to do is save my home and personnal data and start from a fresh install. I've tried this once (with no real success), I intend to read the pages more carefully and give it another try. Many thanks for your time, sorry you wasted it because of me.
