# Install Kata Containers on Ubuntu

> **Notes:**
>
> - Kata Containers packages are available for [Ubuntu\*](https://www.ubuntu.com)
>   versions **16.04** and **18.04** (currently `x86_64` only).
>
> - If you are installing on a system that already has Clear Containers or `runv` installed,
>   first read [the upgrading document](../Upgrading.md).
>
> - If you do not want to copy or type all these instructions by hand, you can use the
>   [`kata-manager`](https://github.com/kata-containers/tests/blob/master/cmd/kata-manager/kata-manager.sh)
>   script to install the packaged system including your chosen container
>   manager. Alternatively, you can generate a runnable shell script from
>   individual documents using the
>   [`kata-doc-to-script`](https://github.com/kata-containers/tests/blob/master/.ci/kata-doc-to-script.sh) script.

1. Install the Kata Containers components with the following commands:

   > **Note:** This installation channel is not secure since the repository currently
   > redirects download URLs to `http`.

   ```bash
   $ sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:/katacontainers:/release/xUbuntu_$(lsb_release -rs)/ /' > /etc/apt/sources.list.d/kata-containers.list"
   $ curl -sL  http://download.opensuse.org/repositories/home:/katacontainers:/release/xUbuntu_$(lsb_release -rs)/Release.key | sudo apt-key add -
   $ sudo -E apt-get update
   $ sudo -E apt-get -y install kata-runtime kata-proxy kata-shim
   ```
