Installing SSH Server
To install software packages on the controller using the Grablo installer or to connect directly to the controller via SSH and SFTP, an SSH server must be installed on the controller. Most Linux distributions, such as Raspberry Pi OS and Debian Linux, come with SSH server pre-installed by default, but some distributions require manual installation by the user.
Open a terminal and enter the following commands to install the SSH server. The controller must be connected to the internet.
sudo apt-get update
sudo apt-get install -y openssh-server
