We can pass apt-get connection through Tor Networks to keep our privacy. To do it, we need proxifying program called Torsocks to help any command line program to work through Tor socks proxy.

After trying SSH Tunneling, probably you feel it is painful to change proxy settings manually every time. And maybe you have another proxy so you need a quick proxy changer. There are extensions to help us change the proxy settings by just a click. It is SwitchySharp for Chrome and Proxy Selector on Firefox. Of course, you may create different proxy configurations as many as possible if you have more than one. I will show you how to install and use it.
