[maemo-users] Error installing maemo 3.1

[From: Oscar Santolalla]

Hello,

I've been trying to install maemo 3.1 with the installer script but I  
always obtain these errors:

-------------------------------------------

My PC has Ubuntu 7.04
I have already added these lines to /etc/apt/sources.list :

deb http://scratchbox.org/debian/ ./
deb http://repository.maemo.org/ bora free non-free
deb-src http://repository.maemo.org/ bora free non-free
deb file:/home/oscar/maemo-sdk-nokia-binaries_3.1 bora explicit

Maybe there is something wrong with my Internet connection?
Thanks a lot,

Oscar
