Problems Installing Beagle on Ubuntu

[Guillermo Latorre <superwillyfoc rastafurbi org>]

Hello everyone!!

I have seen Beagle on the web and I am trying to install it on my
computer. 
I am runnig on Ubuntu Hoary and I am doing all the things described on
the web, the installation tips for Ubuntu.

The problem is:
I have added this line to my /etc/apt/sources.list:

deb http://backports.ubuntuforums.org/backports hoary-backports-staging
main universe multiverse restricted

and I have done a apt-get update and then the ape-get install with all
the packages listed on the web.

But I have a error message from apt-get, and can't download/install the
packages.

I copy the errors at the end of the mail.

Can the repository be down or something?
I have tried also with another apt-get update and with apt-get update
--fix-missing, but nothing... 
I don't know...

Thank you very much!!

Guille
