I want to install Lubuntu on my Raspi 4 and followed the instructions: https://ubuntu.com/download/raspberry-pi, steps 1-4.

At the end I can however not continue to do the lubuntu-desktop installation because wifi is not yet configured and I don't have a wired internet (am always using my mobile's wifi). Likewise I can't install any other package but have to work with the configuration that comes with the server distro.

How can I tell Ubuntu Server which wifi connection details to use?

Thank you very much!

Step 1: In the command line interface run the command

cat /etc/wpa_supplicant.conf

Step 2: At the end of the file, type this lines

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
    network={
         ssid="Your network name/SSID"
         psk="Your WPA/WPA2 security key"
         key_mgmt=WPA-PSK
    }

Example: If the SSID is rocket and password is 12345678 you would add 

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
    network={
         ssid="rocket"
         psk="12345678"
         key_mgmt=WPA-PSK
    }

  • Thank you very much for the quick reply!

    In /etc I don't have a file "wpa_supplicant.conf" but a directory "wpa_supplicant" containing the files "action_wpa.sh", "functions.sh" and "ifupdown.sh".

    Should I create a new file (inside the similarily-named directory?) or modify the existing ones?
