Reading package lists

The installation process was unable to run 'apt-get update' inside the installed targets in order to update the local package database.
This could be due to an error in network configuration inside scratchbox. 
Common causes are incorrect proxy settings and the 'hosts' line in /scratchbox/etc/nswitch.conf.
For the 'hosts' line in /scratchbox/etc/nswitch.conf the following should usually be enough:
hosts:    files dns

Once network issues have been resolved, you should run the installer again.
