I have downloaded the upate to 10.0.1 but this is frozen at
Bundling(100%) for a day.
I can't cancel or delete or do anything with the update.

In the loader-messages.log there are some lines like:

I've checked this url and now (not in previous days) it requires login
to access. It seems any credential of the novell web is valid but there
is no place where put this user in ZCC. Besides this, the
systemupdate.xml doesn't exists in the web.
