---------------------------------------
It seems a mess, but after having been running UBUNTU and some other Linux
versions, I have never been in a situation like this.

as I will be switching to new hardware in about a week I will re-install
everything then, but I still am curious what went/is wrong and how to
repair it.

Thanks, Leo
