# Step 5. - Install Mosquitto on a Raspberry Pi
### First get the repository package signing key, import it into apt, and remove the key file again:
```wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key
sudo apt-key add mosquitto-repo.gpg.key
rm mosquitto-repo.gpg.key```
### Then make the mosquitto repository available to apt:
```cd /etc/apt/sources.list.d/
sudo wget http://repo.mosquitto.org/debian/mosquitto-stretch.list
sudo apt-get update```
### Now we can install the core packages (server & clients):
```sudo apt-get install mosquitto mosquitto-clients```
