How do I turn off proxy in Ubuntu terminal?

How do I remove proxy from Ubuntu 20?

If you are trying to use a proxy on a desktop ubuntu version (for example 19) you can simply add the following line in the /etc/environment file. Edit /etc/environment and add the following two lines: export HTTPPROXY=. Export HTTPSPROXY=. Then restart your computer, that's it! You can use the env command to change environment variables. The env command takes an optional argument which is a name of a variable to be changed. Here, I am going to use a username and password (if they exist) for my proxy, and call the variable HTTPPROXY and HTTPSPROXY. After that, I can then run env without the option argument to see what variables I can export. The other alternative would be to use source. The list may be empty and will be
expanded to a single space-separated list of names. So to set a variable as a global variable for every process, you could do: source /etc/environment. This only works on systems that have the environment file installed in /etc/environment, but most newer distributions should have this.

How to disable proxy terminal Linux?

I want to disable proxy terminal on Linux. I have tried with many solutions online but it didn't work. I even tried to delete the entries from my ~/.bashrc file and ~/.profile file and it did not work.

I am not that tech savy but I really need this fix because all of my work is at a remote location. Please help me out.

This is what you need. Nohup nc -w1 xxx.yyy.zzz 8080 > /dev/null 2>&1 &
