I have looked at the man page:
hence my question in the post above: how do I "mark" a media for updates?
I understand the words, but I'm missing something about the concept.
<{POST_SNAPBACK}>
type in Konqueror:
easyurpmi
and fix your repository
after that:
#urpmi.update -a
and to update your sytem:
#urpmi --auto-select
Thats all!!
