Updating http_proxy environment variable
Solution 1:
You can change the http/https/ftp proxy environmental variables using the following commands:
export http_proxy='http://user:password@prox-server:3128'
export https_proxy='http://user:password@prox-server:3128'
export ftp_proxy='http://user:password@prox-server:3128'
as a one-liner:
export {http,https,ftp}_proxy='http://user:password@prox-server:3128'
These will not persist however, so you may wish to add it to your bashrc.
Solution 2:
Changes to /etc/environment
requires a restart to take effect. First restart your computer and see if your still facing the same problem.
If the problem still exists, open your ~/.bashrc
file and add the proxy entry in this file.
For this to take effect, you have to either restart your terminal or run source ~/.bashrc
