Ubuntu 18 taskbar (Ubuntu Dock) hidden

Question

I'm facing issues recently with Ubuntu 18 after deleting unused kernels by

sudo apt-get autoremove --purge

taskbar is not appearing.

Tapping Super shows taskbar.

Solution

Make sure Ubuntu Dock is installed by running the following command in Terminal

sudo apt install gnome-shell-extension-ubuntu-dock

and then re-login.

Note that if you enable the 'Auto-hide the Dock' option in Ubuntu Dock settings, then the dock would be hidden until mouseover to dodge windows. To make the dock visible all the time launch Settings application and in the 'Dock' section disable 'Auto-hide the Dock'.
