In some environments, before you can access the Internet or external services you must use a proxy server. A proxy server is a network device that sits between your PC and the Internet or external resources. This server makes requests for websites and services on behalf of your PC. A proxy server is usually installed to help save bandwidth, since frequently used resources are cached, to protect computers from ads, malware, and other harmful threats on the Internet. They are commonly used in businesses that want to control what websites you can look at, prevent you from accessing the internet without logging in, or do security checks on websites. By default, Ubuntu is set to automatically detect proxy settings. However, this may not work all the time. To set up a proxy in Ubuntu follow the steps below. First, go to the Ubuntu system menu and select Settings When the Settings pane opens, click on Network to open the panel. Select Network proxy from the list on the right. Choose which proxy method you want to use:

None – The applications will use a direct connection to fetch the content from the web. Manual – For each proxied protocol, define the address of a proxy and port for the protocols. The protocols are HTTP, HTTPS, FTP and SOCKS. Automatic – A URL pointing to a resource, which contains the appropriate configuration for your system.

That should do it. Now go and test your Internet connection to see if you can browse. Applications that use the network connection will use your specified proxy settings.
