# Install `pg_tde` on Debian or Ubuntu

The packages for the tech preview `pg_tde` are available in the experimental repository for Percona Distribution for PostgreSQL 17. 

Check the [list of supported platforms](install.md#__tabbed_1_2).

This tutorial shows how to install `pg_tde` with [Percona Distribution for PostgreSQL](https://docs.percona.com/postgresql/latest/index.html).

## Preconditions

You need the `percona-release` repository management tool that enables the desired Percona repository for you.

    - `wget`
    - `gnupg2`
    - `curl`
    - `lsb-release`
    
    Install them with the following command:
    
    ```bash
    sudo apt-get install -y wget gnupg2 curl lsb-release

    sudo dpkg -i percona-release_latest.generic_all.deb
    ```

    ```

    ```bash
    sudo percona-release enable ppg-{{pgversion17}} experimental
    ```

6. Update the local cache
