# Installation on Debian-family systems

Install the repository:

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

Install the package:

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

Update the package:

```sh
$ sudo apt install pstreamer
```

> **Warning**
>
> The **pstreamer** package requires **aksusbd** version 10.33 or newer. The protection service lies in the same repository, so the package manager pulls it in by itself — no separate step is needed. If, however, the package is installed from a file, bypassing the repository, the installation will stop at dependency resolution until the required version of the service is installed by hand.
>
> Upgrading the protection service is a one-way step, and it does not depend on the type of key. The package places generation 10.33 vendor libraries in `/var/hasplm`, and the previous service does not accept such a library: the licence manager refuses to load it and terminates abnormally. Going back to the previous service without rolling back the whole package as well is therefore not possible. Plan this step as a transition, not as a routine update.

Remove all packages:

```sh
$ sudo apt-get remove pstreamer aksusbd
```
