After I upgraded from 20.04 to 22.04.1 I don't see any icons in Ubuntu's dock. There is only the 9-dot-icon, which opens the applications overview. Even if I try to add an application manually ("add to favourites") the dock stays empty.
What could be the reason? And how can I fix it?
This is how the dock appears at the moment:
edit: I noticed, that the dock icons are present, when I log in with "Gnome" or "Gnome with Xorg", but not with one of the "Ubuntu" options.
Disabling the "Ubuntu Dock" and "Ubuntu AppIndicators" built-in extensions should fix this.
Simply open your applications overview (or "Windows" key) and type "Extensions". Then at the bottom of the window, just disable the Ubuntu Dock and Ubuntu AppIndicators.
A short term solution on a per-occurrence basis is running a command to reload the dock. Press Alt+F2 and then type r then press Return. This will reload and bring the icons back.
Do sudo apt install ubuntu-gnome-desktop --reinstall as suggested by @Cagri.
It worked for me, this happened because I had tried to delete all python packages.
reinstalling of ubuntu-gnome-desktop worked for me(could see the dock options in 22.04v ubuntu) as the dock options was not showing due to deletion and addtion of upgrading the python packages.
