Wifi tray says "Device not ready" in Ubuntu MATE for Raspberry Pi 400

cn flag

Setup

I have installed Ubuntu Server 21.10 on Raspberry Pi 400, configured it as described here and to get desktop environment I have installed Ubuntu MATE by running sudo apt install ubuntu-mate-desktop. I have installed and configured tightvncserver to remote access the machine.

I am able to ssh and vnc to the machine.

Issue

I am not able to manage wifi from the taskbar also taskbar looks incomplete. Screenshot of the desktop.

I have tried few online suggestions like restarting NetworkManager or removing unused packages, but nothing helped.

Not sure if I need to install any missing package, appreciate any help.

PS: I have to go via this route i.e. first configure Ubuntu Server then install desktop environment because I want to do it headless without any external monitor.

You chose difficult path. Ubuntu MATE 21.10 is available from official site: 64-bit - https://ubuntu-mate.org/download/arm64/impish/ ; 32-bit - https://ubuntu-mate.org/download/armhf/impish/ . Fixing device-not ready maybe possible by following https://askubuntu.com/a/1257474/66509 .

Thanks @N0rbert, I can't directly use desktop environment because it require initial setup which require external monitor :(. I was trying the fix over `vnc` but now it doesn't connect to `WiFi`. I have no way to verify it now without external monitor.

Please edit your question to show the result of the commands: `iwconfig` and: `cat /etc/netplan/*.yaml` and, finally: `ps aux | grep Network` Welcome to Ask Ubuntu.

Sure @chili555, I currently don't have external monitor to check it. Will share it after connecting to external monitor.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
