I installed Ubuntu 20.04 LTS Server on my Raspberry Pi 4 8 GB and needed to install
raspi-config is a simple (if long and involved) shell script to configure Pi hardware and Raspbian settings. It is just a front end to the underlying system commands. Found that I need to add Raspberry Pi repository in Ubuntu.
In Ubuntu 20.04 LTS,
bullseye/sid, so it seems to be based on
bullseye (Debian 11.0). Since
http://archive.raspberrypi.org/ does not have
bullseye, I initially chose
buster. Then I changed that to
bullseye is bit newer, perhaps
buster is the safer choice right now.. Code below works for both.
DEB-based distros (Ubuntu, etc.)
To add Raspberry Pi repository in Ubuntu, run the following two commands:
echo deb http://archive.raspberrypi.org/debian/ buster main | sudo tee /etc/apt/sources.list.d/raspberrypi.list
echo deb http://archive.raspberrypi.org/debian/ bullseye main | sudo tee /etc/apt/sources.list.d/raspberrypi.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 7FA3303E sudo apt-get update
That’s it, Raspberry Pi repository will be enabled on the OS and will automatically get updated too.
