After upgrading an Ubuntu Server instance with the ubuntu-desktop-minimal package installed to 22.04, the Dock disappears and won't come back

Failed attempts to remedy this

  • choosing to disable and then enable the Dock in the Settings doesn't work (this seems like it may be a bug as the options appear in the menu to do so, despite as discovered later, the Dock is disabled)
  • attempting in Settings to move the position of the Dock to a different edge of the screen
  • neither reinstalling, nor reconfiguring the package gnome-shell-extension-ubuntu-dock appears to do anything
  • though suggested in a Reddit post, calling dconf reset -f /org/gnome/shell/extensions/dash-to-dock/ doesn't appear to have any effect

Using altF2 and entering lg to bring up the "Looking Glass" (official docs) tool shows that the Dock is disabled (though confusingly offers no way to enable it, nor information as to why it was disabled)
Looking Glass can then (again, confusingly) be quit by going to the Evaluator panel and pressing esc

With this knowledge, gnome-extensions can be used to enable the Dock again

gnome-extensions list  # show Extension package names
gnome-extensions enable ubuntu-dock@ubuntu.com
