wget: unable to resolve host address downloads.sourceforge.net ping: unknown host downloads.sourceforge.net
If you’r host didn’t provided their nameservers that you can use – you can use one provided by OpenDNS.net.
All you need to do is edit file /etc/resolv.comf and add their nemeservers into the file:
nameserver 22.214.171.124 nameserver 126.96.36.199
Save the changes and you’re ready to go!
