Hi there! Let’s get started with just a Raspberry Pi 4 board and a power connector.
In this episode we will:
Flash the Raspberry Pi OS
onto the SD card
and access it via SSH.
No display or Micro HDMI needed.Hardware:
Raspberry Pi 4
How to Set Up a Headless System Without Ever Connecting a Monitor!My System:
OS: Ubuntu 24.04 LTS
Processor: Intel® Core™ i7–9750H × 12 — 8.0 GiB RAMLet's get started!Let’s get started!
0# step— Buy an SD card like this one:
SDCS2/64GB
microSD Memory Card Canvas Select Plus
Read: 100MB/s — Class 10 with SD Adapter
1# step — Install Raspberry Pi OS using Raspberry Pi Imager; To install on Raspberry Pi OS in a Terminal window, type:
sudo apt install rpi-imager2# step —Configure the following settings: Raspberry Pi 4, Raspberry Pi OS (64-bit), and select your SD card. Then click Next:
pi. I’ve also entered my Wi-Fi SSID and password, as well as my location details. Please adjust these settings according to your own setup.
raspberrypi.local. This is the default hostname of the Raspberry Pi, and the .local domain is used to resolve it on a local network through mDNS (Multicast DNS).3# step — Open your Linux terminal and type:
ssh pi@raspberrypi.localj3@j3-LAPTOP:~$ ssh pi@raspberrypi.local

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ED25519 key sent by the remote host is
SHA256:9ipBVAynVWVaGNQkO90MnCZlhIiMsqq9Mw8eVZ0/BWY.
Please contact your system administrator.
Add correct host key in /home/j3/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/j3/.ssh/known_hosts:3
remove with:
ssh-keygen -f '/home/j3/.ssh/known_hosts' -R 'raspberrypi.local'
Host key for raspberrypi.local has changed and you have requested strict checking.
Host key verification failed.
j3@j3-LAPTOP:~$ ssh-keygen -f '/home/j3/.ssh/known_hosts' -R 'raspberrypi.local'
# Host raspberrypi.local found: line 2
# Host raspberrypi.local found: line 3
/home/j3/.ssh/known_hosts updated.
Original contents retained as /home/j3/.ssh/known_hosts.old
j3@j3-LAPTOP:~$ ssh pi@raspberrypi.local
The authenticity of host 'raspberrypi.local (192.168.0.114)' can't be established.
ED25519 key fingerprint is SHA256:9ipBVAynVWVaGNQkO90MnCZlhIiMsqq9Mw8eVZ0/BWY.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

pi@raspberrypi:~ $This issue occurred because I already had an entry for the Raspberry Pi in my known_hosts file. If you haven’t accessed it before, you will be prompted with the message, Are you sure you want to continue connecting (yes/no/[fingerprint])? Simply type “yes” to proceed.
4# step — To update and configure your Raspberry Pi, type:
sudo raspi-config

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
This disk is currently in use - repartitioning is probably a bad idea.
It's recommended to umount all file systems, and swapoff all swap
partitions on this disk.
