Switching from GDM (GNOME Display Manager) to LightDM on Ubuntu 20.04 LTS broke "Search your computer" functionality.

Fix found:

  1. apt install ubuntu-unity-desktop
  2. apt remove gnome-shell
  3. dpkg-reconfigure lightdm
  4. reboot
  • What did you search for that resulted in the error? Do other searches for common programs work such as "Terminal" or "Firefox"?

I had the exact same problem.

You will need to install unity. Try this:

sudo apt-get install unity
sudo systemctl daemon-reload
sudo service lightdm restart

The commands will ask for your password.
