Learn how to – How To Install Ruby on Ubuntu 22.04|20.04|18.04.
In this guide, we will look at how to Install Ruby Programming Language on Ubuntu 22.04/20.04/18.04 Linux machine. Ruby is a dynamic, open source, object-oriented scripting language created with simplicity and productivity in mind.
The easiest way to Install Ruby on Ubuntu 22.04/20.04/18.04 is from a PPA repository. For this, we will use the Brightbox PPA repository. Brightbox has been providing optimized Ruby packages for Ubuntu for years.
We will also consider other methods of installation Ruby on Ubuntu 22.04/20.04/18.04:
- Install Ruby using RVM
- Install Ruby using Rbenv
Method 1: Install Ruby on Ubuntu 22.04|20.04|18.04 using RVM
You can also install Ruby using RVM. RVM is a command-line tool which allows you to easily install, manage, and work with multiple ruby environments from interpreters to sets of gems.
Install key dependency packages:
sudo apt update
sudo apt install build-essential curl git libssl-dev libreadline-dev bison zlib1g-dev autoconf libgdbm-dev libyaml-dev libreadline-dev libncurses5-dev libffi-dev gnupg2Import RVM GPG key:
$ gpg2 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
gpg: key 105BD0E739499BDB: public key "Piotr Kuczynski <piotr.kuczynski@gmail.com>" imported
gpg: key 3804BB82D39DC0E3: new key but contains no user ID - skipped
gpg: Total number processed: 2
gpg: w/o user IDs: 1
gpg: imported: 1
# OR
curl -sSL https://rvm.io/mpapis.asc | sudo gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | sudo gpg --import -Then install RVM on Ubuntu 20.04/18.04 by running the command:
curl -sSL https://get.rvm.io | bash -s stable
source $HOME/.rvm/scripts/rvmSample successful installation output:
Installing RVM to /home/learnhowto/.rvm/
Adding rvm PATH line to /home/learnhowto/.profile /home/learnhowto/.mkshrc /home/learnhowto/.bashrc /home/learnhowto/.zshrc.
Adding rvm loading line to /home/learnhowto/.profile /home/learnhowto/.bash_profile /home/learnhowto/.zlogin.
Installation of RVM in /home/learnhowto/.rvm/ is almost complete:
* To start using RVM you need to run `source /home/learnhowto/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
Thanks for installing RVM

NOTE: with this method you won’t get the latest release of Ruby installed on your system.
I like the Brightbox PPA repository because it gives you the flexibility to install any version of Ruby they maintain and update from package manager:
Add PPA repository to your Ubuntu 22.04/20.04/18.04 system using the commands:
