I did sudo apt upgrade
and restarted Ubuntu 20.04 system. However, after login the Dock is missing from the desktop environment. The Dock does appear on the left edge of the monitor when I press the Super
button to enter the Activities
screen.
I have tried solutions 1 and also doing
$ sudo apt install gnome-shell-extension-ubuntu-dock
$ sudo dpkg-reconfigure gnome-shell-extension-ubuntu-dock
Each time reboot to check the appearance of the dock. Still missing.
noticed something strange in Settings
--> Appearance
--> Dock
. Icon size
is 0 and can't be changed and Show on
is blank. Position on screen
was initially blank. I could selected any of the options but Dock still does not appear. See image
Quite sometime ago, I had installed Dash-to-Dock
and uninstalled it. Dock still appears and worked well for weeks until this upgrade. According to apt log, the affected packages were:

How do I get the Dock to reappear?
Update
@vanadium I can't enable Ubuntu Docks from Extension
or Tweaks
. See below. Can't do your step 4.
