It wanted to remove a lot of Xfce files - I can live with that..... I have to admit that it must be hard to upgrade a system with Gnome KDE and Xfce like I have....
--- Still updating and looking good.....
And I ended up with a several pages long list to fix. Same thing as with urpmi it just toke longer.
Rebooting......
Fresh install it is

....
That installer is realy easy and intuitive. It finds all the partitions and sugests to use the ones that are alreaddy there. It also sugests to Format / and leave /home as is. So basically I just have to press next.....
Some lousy English in the animations while installing like:
Correct me if I am wrong, but that sounds like a description of an already given support (no biggie).....Sphere: Our tech support became closer to you
And finished (that was fast!). Rebooting.......
And now it is time to pick the language. Norwegian is suggested and the computer is frozen
Turned out it was just a really long wait..... moving on

Just checking, I see one of my disks is still missing, so my problem is not, really, solved.
