How do I use a proxy which contains a user and password?

I wanted to set a proxy on my machine, However, the network proxy option in settings doesn't have a user:pass field, which is required to get my SOCK5 proxy working. This is my first time using Linux so I'm not very thorough with the terminal.

Distributor ID: Ubuntu
Description:    Ubuntu 21.10
Release:    21.10
Codename:   impish 

If you want to set this for all users on the system edit

sudo nano /etc/environment

and add

export HTTP_PROXY="{user}:{pwd}@{proxy--address}:{port}"
export HTTPS_PROXY="{user}:{pwd}@{proxy--address}:{port}"
export FTP_PROXY"{user}:{pwd}@{proxy--address}:{port}"
export NO_PROXY="localhost,127.0.0.1,::1"

If you want it for a single user you can put those lines in

sudo nano ~/.bashrc

That method allows for a different proxy for each user. If you need a proxy for apt:

sudo nano /etc/apt/apt.conf

and add

Acquire::http::Proxy "http://{user}:{pwd}@ {proxy-address}:{port}";
Acquire::https::Proxy "http://{user}:{pwd}@ {proxy-address}:{port}";
