How to install Ruby Version Manager (RVM) on Debian 11 Bullseye

Ruby Version Manager is a command-line tool for installing & managing multiple Ruby interpreters and versions as well as gem sets simultaneously on the same computer. Installing RVM  on Debian 11 bullseye or 10 buster will also help the users to get the latest version of Ruby instead of sticking to the one supplied through the Debian default repository.

Therefore, this Ruby Version Manager offers flexibility to developers working on various projects with different requirements.

Steps to install RVM on Debian 11 Bullseye

You just need a user with sudo rights to perform this tutorial and the steps given here can be used for Debian 10 Buster as well.

Run System update

Update the installed packages and refresh the repository cache using the update command. Also, along with that install the cURL tool.

sudo apt update
sudo apt install curl


Add Ruby Version Manager GPG key

To let the system confirm the packages we get to install the RVM- Ruby Version Manager are from an authentic source, we will add the GPG key used to sign the RVM packages.

curl -sSL | gpg --import -
curl -sSL | gpg --import -

Import RVM GPG keys for Debian 11


Run RVM Installation script on Debian 11 Bullseye

Next, run the curl command to download and install the RVM using script from GitHub on your Debian 11 Linux.

curl -sSL | bash -s stable

Reload Debian 11 or 10 Shell

After the installation, to let the system properly integrate the RVM home path to the system environment variable, either close the terminal app and open it again or simply reload the shell session using the given command:

source ~/.bashrc


Check available Ruby version to install

Now, we can use the RVM command to install and manage Ruby versions on our Debian Linux. Run this command to list what are the available versions:

rvm list known

List ruby versions to install


Ruby Installation

Now, to install the latest version, run:

rvm install ruby

for some specific version, mention that:

rvm install 3.0

Requirements installation failed with status 100.


Note: if you get this error while installing Ruby:

please read /home/h2s/.rvm/log/1635778195/package_install_patch_g++_gcc_autoconf_automake
Requirements installation failed with status: 100.

Then perform the following things:

Edit source file:

sudo nano /etc/apt/sources.list

Paste the following repo at the end of the file.

deb sid main contrib non-free

Save it by pressing Ctrl+O, hit the Enter key, and exit it using Ctrl+X.

Add SID repository in Debian 11

Run system update:

sudo apt update

Install following dependencies:

sudo apt install patch g++ gcc autoconf automake bison libc6-dev libffi-dev libgdbm-dev \
libncurses5-dev libsqlite3-dev libtool libyaml-dev make patch sqlite3 zlib1g-dev \
libgmp-dev libreadline-dev libssl-dev
