# Installing the beta version

Beta version 2.1 is installed from a separate beta repository on the same server, `repo.pstreamer.tv`. The packages and metadata of the beta repository are signed with the same key as the stable repository; the key fingerprint and how to install the key are given in [Installation on RHEL-family systems](rhel.md#install-rhel) and [Installation on Debian-family systems](debian.md#install-debian).

The beta repository holds only the `pstreamer` package, and it needs a licence to run; a valid version 2.x licence also works for the beta. There is no demo edition in the beta channel: the `pstreamer-demo` package stays on the stable version 2.0.2. The terms of participation, reporting problems and going back to the stable version are described in [Beta testing programme](../extras/beta.md#extras-beta).

The beta repository is added on top of the stable one: the package manager takes `pstreamer` from the repository with the newer version, that is, from the beta repository.

> **Note**
>
> The beta repository is connected alongside the stable 2.x repository (`pstreamer2`), and that one must stay connected: the protection service aksusbd and the transcoders are installed from it. Disable the 1.x repository (`/etc/yum.repos.d/pstreamer.repo` or `/etc/apt/sources.list.d/pstreamer.list`): otherwise, when you leave the beta, the package manager may downgrade the node to 1.x (A node on version 1.x).

> **Note**
>
> Before you move from the stable version to the beta, save a copy of the settings file `/opt/pss/config/pss.json` (if the file already exists) under a new name, for example `pss.json.$(date +%Y%m%d_%H%M%S)`. With it, going back to the stable version loses no setting ([How to go back to the stable version](../extras/beta.md#extras-beta-leave)).

## Debian family systems

Add the stable repository and the key if they are not added yet ([Installation on Debian-family systems](debian.md#install-debian)), then the beta repository:

```sh
$ sudo wget https://repo.pstreamer.tv/pub/deb/dists/pstreamer2-beta/pstreamer2-beta.list -O /etc/apt/sources.list.d/pstreamer2-beta.list
$ sudo apt-get update
```

To install the beta version or upgrade the stable one to it:

```sh
$ sudo apt-get install pstreamer
```

The command `apt-cache policy pstreamer` shows which version is installed and which repository it came from.

## RHEL family systems

Add the beta repository for RHEL 7:

```sh
$ sudo yum install yum-utils
$ sudo yum-config-manager --add-repo=https://repo.pstreamer.tv/pub/pstreamer2-beta/pstreamer2-beta.repo
```

Or for RHEL 8+:

```sh
$ sudo yum config-manager --add-repo=https://repo.pstreamer.tv/pub/pstreamer2-beta/pstreamer2-beta.repo
```

The repository file goes to `/etc/yum.repos.d/pstreamer2-beta.repo`. If the stable repository is not added yet, add it too ([Installation on RHEL-family systems](rhel.md#install-rhel)).

To install the beta version:

```sh
$ sudo yum -y install pstreamer
```

To upgrade the stable version to it:

```sh
$ sudo yum -y update pstreamer
```

> **Note**
>
> In **openSUSE**, the beta repository is added with `sudo zypper addrepo https://repo.pstreamer.tv/pub/pstreamer2-beta/pstreamer2-beta.repo`, and the upgrade is `sudo zypper refresh` and `sudo zypper update pstreamer`.

After installation

On a new server, [activate the service and configure its initial settings](../first_start/index.md#first-start-activation) as with a normal installation. A node upgraded from the stable version keeps its licence and settings.

## A node on version 1.x

If the node runs version 1.x — including after an accidental downgrade to it — the 2.x package stops the upgrade: version 2.0.2 and later do not accept a licence key issued for a version older than 2.0.2, and the service would not start after such an upgrade. On RHEL the upgrade aborts with the message `Error in PREIN scriptlet` and no explanation.

1. Get an updated V2C licence file from your supplier. With a trial licence this step is not needed.
2. Disable the 1.x repository and connect the stable 2.x repository ([Installation on RHEL-family systems](rhel.md#install-rhel), [Installation on Debian-family systems](debian.md#install-debian)).
3. Confirm the upgrade in advance and upgrade the package:

   ```sh
   $ sudo touch /opt/pss/config/lic-key-updated
   $ sudo yum -y update pstreamer
   ```

   Instead of the file, you can set the variable `PSS_LICENSE_KEY_UPDATED=1` in the environment of the upgrade command. On Debian the upgrade is `sudo apt-get install pstreamer`.
4. Apply the updated key ([Permanent activation](../first_start/index.md#first-start-permanent-activation)); with a trial licence, run `/opt/pss/tools/activate.sh` without arguments.
