Hey guys, how have you been?

Today, we are going to learn how to install RVM on Deepin OS 20.7, a Debian based distro.
Actually, this procedure can be done in any Debian based distro.

Introduction

RVM is a command-line tool that allows you to easily install, manage, and work with multiple ruby environments from interpreters to sets of gems. It was originally started in October of 2007.

Ruby Version Manager, often abbreviated as RVM, is a software platform for Unix-like operating systems designed to manage multiple installations of Ruby on the same device.

1 - Update your system

Open the terminal and run the following command:

sudo apt update && apt upgrade

2 - Install the required dependencies

sudo apt install apt-transport-https ca-certificates gnupg2 curl

3 - Import GPG Key

GPG stands for Gnu Privacy Guard and it is supported by the Internet Engineering Task Force (IETF) through the RFC 4880.

The IETF publishes RFCs authored by network operators, engineers, and computer scientists to document methods, behaviors, research, or innovations applicable to the Internet.

GnuPG (more commonly known as GPG) is an implementation of a standard known as PGP (Pretty Good Privacy). It uses a system of "public" and "private" keys for the encryption and signing of messages or data.

curl -sSL https://rvm.io/pkuczynski.asc | gpg2 --import -

4 - Install the RVM stable version

curl -sSL https://get.rvm.io | bash -s stable --ruby

By now, you should be able to see something like this:

rvm -v

You should be able to see something like this:

6 - List all Ruby versions available

rvm list known

You should be able to see something like this:
