I recently installed Ubuntu Server LTS 16.04.3. I decided to add a minimal GUI using the command commonly recommended for doing so:
sudo apt-get install --no-install-recommends ubuntu-desktop
What I got was a GUI that doesn't recognize any commands. I can't even get a terminal window to appear. Typing any text in the Search bar results in "Sorry, there is nothing that matches your search", regardless of what I enter. The installation is now essentially useless because I can't initiate any actions. What am I doing wrong?
