thx! worked after changing the mirror.
Went til the end, with one error:
The following packages have unmet dependencies:
pluto-asterisk: Depends: pluto-voicemail-monitor but it is not going to be installed
PreDepends: asterisk-pluto but it is not going to be installed
E: Broken packages
Try 0 failed with exit code 100

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming..
Any idea why? Both are in http://download.linuxmce.org/ubuntu/dists/intrepid/beta2/binary-i386/
