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 . – N0rbert Jan 18 '22 at 11:36
  • 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. – HelioVaGator Jan 18 '22 at 12:43
  • 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. – chili555 Jan 18 '22 at 14:31
  • Sure @chili555, I currently don't have external monitor to check it. Will share it after connecting to external monitor. – HelioVaGator Jan 18 '22 at 15:19
