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.
Best regards,
J.-Luc
