SSH into Raspberry Pi Running Ubuntu 22.04 Server LTS

Question

I managed to flash Ubuntu 22.04 LTS Server on a 32 GB SD card using RasPi Imager where I also configured my WLAN. I then connect the RasPi's Micro USB to the USB port of my Linux machine and I was hoping that I could log in, but for some reason I do not see my RasPi listed on my router.

Is there an idea on how I could find the host of my RasPi so that I can SSH into it? I also do not have an external monitor to connect my RasPi to. Any thoughts?

Answer 1

Here is how I solved it.

1. I inserted the SD card (after flashing the OS image on it) in my computer

2. I opened the boot partition and added an empty file called ssh

3. I connected my Raspberry Pi via an Ethernet cable to my home router

4. Find WiFi card name

   $ ls /sys/class/net
   eth0  lo  wlan0
   

5. Edit the network configuration file:

   sudo nano /etc/netplan/50-cloud-init.yaml
   

# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    version: 2
    wifis:
        renderer: networkd
        wlan0:
            access-points:
                MySSID:
                    password: MyPassWord
            dhcp4: true
            optional: true

6. Update MySSID and MyPassword with my WiFi connections and then reboot.
