### Steps to install OpenProject on Debian 8 (Jessie) All steps need to be run as `root`. **1. Import the packager.io repository signing key** Import the PGP key used to sign our packages. Since we're using the _packager.io_ platform to distribute our packages, both package source and signing key are tied to their service. ```bash wget -qO- https://dl.packager.io/srv/opf/openproject-ce/key | sudo apt-key add - ``` **2. Install apt-https suppport** Since we only provide https package sources, you may need to install `apt-transport-https` as a preliminary step. ```bash apt-get install apt-transport-https ``` **3. Add the OpenProject package source** ``` sudo wget -O /etc/apt/sources.list.d/openproject-ce.list \ https://dl.packager.io/srv/opf/openproject-ce/stable/8/installer/debian/8.repo ``` **4. Install the OpenProject Community Edition package** Using the following commands, apt will check the new package source and install the package and all required dependencies. ```bash apt-get update apt-get install openproject ```
