Your problem is not ubuntu based, but is network issue. If you closely see it says : error are below wget: unable to resolve host address ‘github.com’ which means that your DNS server cannot find github.com . Check your /etc/resolv.conf and try to ping or dig github.com after you fix your dns server issue.

  • Hello guys !! This OPENCV script works well for ubuntu 15.10. Why i don't know. But i have tried it on Ubuntu 15.10 AND successfully installed the OPENCV. – Abhishek Raj Feb 23 '16 at 11:25
