On Debian and Ubuntu

In Debian derived distributions, you can use the official Crystal repository.

Setup repository

First you have to add the repository to your APT configuration. For easy setup just run in your command line:

curl https://dist.crystal-lang.org/apt/setup.sh | sudo bash

That will add the signing key and the repository configuration. If you prefer to do it manually, execute the following commands as root:

apt-key adv --keyserver keys.gnupg.net --recv-keys 09617FD37CC06B54
echo "deb https://dist.crystal-lang.org/apt crystal main" > /etc/apt/sources.list.d/crystal.list
apt-get update


Once the repository is configured you're ready to install Crystal:

sudo apt-get install crystal

Sometimes you will need to install the package build-essential in order to run/build Crystal programs. You can install it with the command:

sudo apt-get install build-essential


When a new Crystal version is released you can upgrade your system using:

sudo apt-get update
sudo apt-get install crystal
