Ubuntu Server 20.10 Wifi setup on Raspeberry

[lseabra2]

Hi,

I'm following the steps on https://discourse.ubuntu.com/t/how-to-i ... y-pi/14660 to setup Ubuntu Server 20.10 on a Raspbery Pi 4.

I set up the wifi details as indicated on step "Getting setup with Wi-Fi" but I can't get it to work.

The file /etc/netplan/50-cloud-init.yaml is correctly generated but on running "sudo netplan --debug generate" I get the message "NetworkManager: definition wlan0 is not for us (backend1)".

Any ideas about what's going on?

Thanks!

"wlan0" is probably NOT the correct name.

The linked article is for an older version and probably not up to date for 20.10.

If you can use the desktop image (ubuntu-20.10-preinstalled-desktop-arm64+raspi.img), I can recommend it because the installer configured WLAN without any problems.

May we see the exact netplan yaml file?

Is Network Manager actually installed?

sudo dpkg -s network-manager | grep Status

If it is installed, it will be easier to manage the wireless with NM than netplan.

Also, please show us:

ip addr show
