+How to Set Proxy Settings for APT Command
+======
+
+In this guide, you will learn how to set proxy settings for the APT command in Ubuntu/Debian Linux distributions.
+
+A proxy server is an intermediary server that sits between a client system or end user requesting the resource and the resource itself. In most cases, a proxy server acts as a gateway between end users and the internet.
+
+For organizations and enterprise environments, a proxy server provides a number of benefits. It controls internet usage by blocking sites that are deemed to impact employees’ productivity. It also enhances privacy and improves the organization’s security through data encryption.
+
+There are several ways to set proxy settings for apt command, so let’s jump right in.
+
+Note: For demonstration, we will use Ubuntu 22.04.
+
+### Configure Proxy Setting For APT Using A Proxy file
+
+The easiest way to configure proxy settings for the APT command is by creating a proxy.conf file as shown.
+
+```
+$ sudo vi /etc/apt/apt.conf.d/proxy.conf
+```
+
+For a proxy server without a username and password, add the following entries as shown
+
+For the HTTP Proxy, add the following entry:
+
+```
+Acquire::http::Proxy "http://proxy-IP-address:proxyport/";
+```
+
+Do the same for the  HTTPS Proxy:
+
+```
+Acquire::https::Proxy "http://proxy-IP-address:proxyport/";
+```
+
+Example:
+
+```
+$ cat  /etc/apt/apt.conf.d/proxy.conf
+Acquire::http::Proxy "http://192.168.56.102:3128/";
+Acquire::https::Proxy "http://192.168.56.102:3128/";
+```
+
+If your Proxy server requires a username and password details, add them as follows
+
+```
+Acquire::http::Proxy "http://username:[email protected]:proxyport";
+Acquire::https::Proxy "http://username:[email protected]:proxyport";
+```
+
+Example:
+
+```
+$ cat  /etc/apt/apt.conf.d/proxy.conf
+Acquire::http::Proxy "http://[email protected]#@192.168.56.102:3128/";
+Acquire::https::Proxy "http://[email protected]#@192.168.56.102:3128/";
+```
+
+Once you are done, Save the changes and exit the configuration file. The Proxy settings will come into action the next time you run the APT package manager.
+
+For example, you can update the local package index and then install net-tools package
+
+```
+$ sudo apt update
+$ sudo apt install net-tools -y
+```
+
+Verify the proxy server logs to confirm that apt command is using proxy server for downloading packages. On the proxy server run,
+
+```
+# tail -f /var/log/squid/access.log  | grep -i 192.168.56.240
+```
+
+Here ‘192.168.56.240’ is the IP address of our Ubuntu machine,
+
+Perfect, output above confirms that apt command of our ubuntu system is downloading the packages via proxy server (192.168.56.102)
+
+### An Alternative Way of Specifying Proxy Details
+
+Apart from the first approach, you can specify the proxy details in a much simpler way. Once again, create a proxy.conf file as follows.
+
+```
+$ sudo vi /etc/apt/apt.conf.d/proxy.conf
+```
+
+For a Proxy server without a username and password, define it as shown.
+
+```
+Acquire {
+  http::Proxy "http://proxy-IP-address:proxyport/";
+  https::Proxy "http://proxy-IP-address:proxyport/";
+}
+```
+
+Sample example file would look like below,
+
+```
+$ sudo vi /etc/apt/apt.conf.d/proxy.conf
+```
+
+For a Proxy server with username and login details:
+
+```
+Acquire {
+   http::Proxy "http://username:[email protected]:proxyport/";
+   https::Proxy "http://username:[email protected]:proxyport/";
+}
+```
+
+Save the changes and exit the configuration file. Just a reminder that these settings take immediate effect once you start using the APT package manager.
+
