Cannot pin KeePassX to task bar

[Thomas]

Installing KeePassX on Ubuntu 20.10 through "Ubuntu Software" succeeds, but the only way to launch the application is using the terminal. It will not show anywhere and cannot even be searched for in the activity screen (or whatever it is called). Once launched through the terminal, it cannot be added to the task bar. While there is an "Add to Favorites" menu item, it doesn't do anything. Also dragging the icon to a specific location does not work.

I also tried uninstalling the application and building it from git master directly, but it has the same issue.

This worked fine on Ubuntu 20.04.
