how to set proxy in ubuntu 25.04 command line

Setting a proxy on Ubuntu 25.04 via command line is useful for controlling internet access and routing traffic.

Step 1: Set a Temporary Proxy

This method sets the proxy only for the current terminal session; it resets after closing the terminal:

export http_proxy="http://proxy.example.com:8080"
export https_proxy="http://proxy.example.com:8080"

Check if the proxy variable is set:

echo $http_proxy

Step 2: Configure Proxy for a Single User

To keep the proxy active for your user across terminal sessions, add the settings to your shell profile:

nano ~/.bashrc

Add these lines to the end of .bashrc, then reload it:

export http_proxy="http://proxy.example.com:8080"
export https_proxy="http://proxy.example.com:8080"
source ~/.bashrc

Step 3: Set a System-wide Proxy

Set the proxy for all users and services by editing the system environment file:

sudo nano /etc/environment

Add the following lines and save the file:

http_proxy="http://proxy.example.com:8080"
https_proxy="http://proxy.example.com:8080"

Step 4: Configure Proxy for APT

APT requires a separate proxy configuration for package management:

sudo nano /etc/apt/apt.conf.d/95proxies

Add these lines to enable proxy for APT:

Acquire::http::Proxy "http://proxy.example.com:8080/";
Acquire::https::Proxy "http://proxy.example.com:8080/";

Step 5: Set Proxy for Snap

Snap requires its own proxy settings configured via snap commands:

sudo snap set system proxy.http="http://proxy.example.com:8080"
sudo snap set system proxy.https="http://proxy.example.com:8080"

Verify the Snap proxy configuration:

snap get system
