Comment 4 for bug 815252

I bypassed Internet Connection thing by removing ping line from dl-script.sh, but I'm not able to run apps. During it's routine script gives me this
Error reading https://launchpad.net/api/1.0/~elementaryart/+archive/unstable-upstream: <urlopen error [Errno 0] Error>

After that, the shell gives errors that gaffel is not found. I guess that the script fails to install gaffel into sandbox. Anyway, I'm able to open this link, why the script can't?
