The symptoms are that you receive an error after entering the wget line: 'GnuTLS: A TLS fatal alert has been received.' If (only if) you get this error, paste the following command in, and press return.
Code: Select all
sudo sed -i 's/^#name_servers.*/name_servers=8.8.8.8/' /etc/resolvconf.conf
Then reboot, and try again. The command asks your RPi to use Google's DNS, not your ISP's DNS.
