This ^^^ isn't right>
Perhaps the server is updating.
I don't think so as I am one of the very few people who have access to the pardususer.de repo server.
In fact I am doing 99,9% of the maintenance of this repo.
And the file pisi-index.xml.xz.sha1sum is present.
You can check yourself by
wget http://pakete.pardususer.de/pardus-2011/i686/pisi-index.xml.xz.sha1sum
It is only 40 bytes.
And see also my results from last night, which don't show any problem.
I will do r re-index of the pardususer.de repo just to make sure.
This will take place in ~ 15 minutes.
