In this guide, we are going to learn how to set system wide proxy in Ubuntu 18.04. Imagine you are in a local network environment where access to the Internet is also possible when you are going through a proxy server<\/a>. Well, in this guide we are gonna learn how to configure system wide proxy settings on your Ubuntu 18.04 server or desktop so that you can be able to access the Internet.<\/p>\n\n\n\n

Setting System Wide Proxy in Ubuntu 18.04<\/a><\/h2>\n\n\n\n

Set System Wide Proxy using Environment Variables<\/h3>\n\n\n\n

One of the ways of configuring system wide proxy settings on Ubuntu 18.04 system is by using environment variables especially if you are running an headless server. Proxy environment variables depend on the protocol handlers used by your proxy server. This can either be http<\/code>, https<\/code>, ftp<\/code> or socks<\/code>.<\/p>\n\n\n\n

Hence to set http or https proxy environment variables, use the export<\/code> command.<\/p>\n\n\n\n

export http_proxy=http:\/\/192.168.43.100:3128<\/pre>\n\n\n\n
export https_proxy=https:\/\/192.168.43.100:3128<\/pre>\n\n\n\n
Note that the export<\/code> command sets temporarily environment variables that are only persistent on the shell you created the variable and the user who created the variable.<\/p>\n\n\n\n
Hey, you want to learn how to configure Squid proxy and Squid Proxy authentication on CentOS 7\/Fedora 29? Check the links below;<\/p>\n\n\n\n

To set the proxy environment variables to apply to all the system users or persistent across all shells, you can append these lines to \/etc\/environment<\/code>.<\/p>\n\n\n\n
echo -e \"http_proxy=http:\/\/192.168.43.100:3128\/\\nhttps_proxy=https:\/\/192.168.43.100:3128\/\" | sudo tee -a \/etc\/environment<\/pre>\n\n\n\n
http_proxy=http:\/\/192.168.43.100:3128\/\nhttps_proxy=https:\/\/192.168.43.100:3128\/<\/pre>\n\n\n\n
Note that these settings will only take effect on login again since the \/etc\/environment<\/code> is read on system login. However, you can still use netplan<\/code> command to apply the settings.<\/p>\n\n\n\n
sudo netplan apply<\/pre>\n\n\n\n
To test this out, try to download anything from the terminal or run the system update. You will see that the connections is happening through the proxy server.<\/p>\n\n\n\n
wget google.com\n--2019-03-23 12:34:05--  http:\/\/google.com\/\nConnecting to 192.168.43.100:3128<\/strong>...<\/pre>\n\n\n\n
sudo apt update\n0% [Connecting to 192.168.43.100<\/strong> (192.168.43.100)] [Connecting to 192.168.43.100 (192.168.43.100)]...<\/pre>\n\n\n\n
To configure proxy settings for APT only, you can simply create proxy configuration file under \/etc\/apt\/apt.conf.d\/<\/code>.<\/p>\n\n\n\n
echo -e 'Acquire::http::Proxy \"http:\/\/192.168.43.100:3128\/\";\\nAcquire::https::Proxy \"https:\/\/192.168.43.100:3128\/\";' | sudo tee \/etc\/apt\/apt.conf.d\/02proxy<\/pre>\n\n\n\n
Acquire::http::Proxy \"http:\/\/192.168.43.100:3128\/\";\nAcquire::https::Proxy \"https:\/\/192.168.43.100:3128\/\";<\/pre>\n\n\n\n
If your proxy server requires username\/password authentication, then the environment variables would set as below;<\/p>\n\n\n\n
http_proxy=http:\/\/U<\/strong>sername:Password<\/strong>@192.168.43.100:3128\/\nhttps_proxy=https:\/\/U<\/strong>sername:Password<\/strong>@192.168.43.100:3128\/<\/pre>\n\n\n\n
For APT;<\/p>\n\n\n\n
Acquire::http::Proxy \"http:\/\/U<\/strong>sername:Password<\/strong>@192.168.43.100:3128\/\";\nAcquire::https::Proxy \"https:\/\/U<\/strong>sername:Password<\/strong>@192.168.43.100:3128\/\";<\/pre>\n\n\n\n
If you are looking at running at command for just that moment via proxy, you may prefix apt command with proxy settings as shown below;<\/p>\n\n\n\n
sudo 'http_proxy=http:\/\/192.168.43.100:3128' apt update<\/pre>\n\n\n\n
or<\/p>\n\n\n\n
sudo 'http_proxy=http:\/\/Username:Password@192.168.43.100:3128' apt update<\/pre>\n\n\n\n
