Setting proxy from terminal

1. For gtk3 programs such as rhythmbox and online accounts:

First you need to enter proxy settings in network settings (along with authentication):

Then apply system wide.

2. For apt,software center etc

edit the file /etc/apt/apt.conf

And then replace all the existing text by the following lines

  1. Acquire::http::proxy "http://username:password@host:port/";
  2. Acquire::ftp::proxy "ftp://username:password@host:port/";
  3. Acquire::https::proxy "https://username:password@host:port/";

 

configure proxy for apt in ubuntu 18.04

Creating  an Apt Proxy Conf File

Apt loads all configuration files under /etc/apt/apt.conf.d. We can create a configuration specifically for our proxy there, keeping it separate from all other configurations.

  1. Create a new configuration file named proxy.conf. 
    sudo touch /etc/apt/apt.conf.d/proxy.conf
  2. Open the proxy.conf file in a text editor. 
    sudo vi /etc/apt/apt.conf.d/proxy.conf
  3. Add the following line to set your HTTP proxy. 
    Acquire::http::Proxy "http://user:password@proxy.server:port/";
  4. Add the following line to set your HTTPS proxy. 
    Acquire::https::Proxy "http://user:password@proxy.server:port/";
  5. Save your changes and exit the text editor.

Your proxy settings will be applied the next time your run Apt.

 

3. Environment variables

edit the file /etc/environment

And then add the following lines after PATH="something here"

  1. http_proxy=http://username:password@host:port/
  2. ftp_proxy=ftp://username:password@host:port/
  3. https_proxy=https://username:password@host:port/

 

set Repositories.

https://help.ubuntu.com/community/Repositories/CommandLine

Ubuntu uses apt for package management. Apt stores a list of repositories or software channels in the file

/etc/apt/sources.list

and in any file with the suffix .list under the directory

/etc/apt/sources.list.d/
