Adding Proxy Settings to Raspberry Pi

In many cases you need to configure a proxy to be able to connect your Raspberry Pi to the internet. This guide will help you with that. 

Prerequisites

1. This guide assumes that you're running Raspbian Jessie or a similar derivate (think Ubuntu) on your machine.

Setting up the system-wide proxy

1. For setting the proxy system-wide we need to change the /etc/environment file. In this case "nano" was used as the text editor but you can also use your preffered one.

   sudo nano /etc/environment

2. Substitute your own proxy information and add the following lines to the file and save them.

   httpproxy=http://proxy:port httpsproxy=http://proxy:port

3. Reboot your system and you should be all set up.

   sudo reboot

4. Note: Implementing changes to the /etc/environment file is the proper way of setting the proxy. But in some cases this does not work, so you might consider implementing the changes also into the /etc/profile file or the ~/.profile file.

   sudo nano /etc/profile sudo nano ~/.profile

5. Proceede as specified above and then it should work for you as well.

Configure "apt-get" for proxy

To be able to use "apt-get" we need to configure the proxy. For this we need to run the following steps:

1. Create a new file with an editor (here: nano):

   cd /etc/apt/apt.conf.d sudo nano 10proxy

2. Add one of the following lines, depending on whether or not an authentication needs to be included and replace the placeholders with your proxy information.

   Acquire::http::Proxy "http://proxy:port/"; Acquire::http::Proxy "http://username:password@proxy:port/";

3. Save and then reboot your Raspberry Pi and you should be able to run an update.
