I just upgraded from Ubuntu 20.10 to Ubuntu 21.04.
Presently there are two software centers on my system, as you can see here:

If I left-click on "Ubuntu Software", nothing happens: the application does not launch.
If I right-click on "Ubuntu Software" and I select "Show details", the application launches, albeit showing a message "Sorry! There are no details for that application" (but at least it starts)
The expected behaviour would be that, when I clic on the icon, the application starts... Any suggestions ?
Thanks!
