Im using Ubuntu 20.04. Some time ago, the gnome software app had disappeared, so I reinstalled it using apt-get install gnome-software
Now after a recent update, I'm seeing two software applications, one named 'Software' which was there before, and another named 'Ubuntu Software.' I checked the package list, but I see no new packages.
Some other answers say that the second one is 'ubuntu-software-center' but that is not the case, I checked.
Moreover, I tried uninstalling 'gnome-software', and the old one I installed, i.e. 'Software' goes away, and the new one stays. However, when I right click an application, I no longer have the option to view the details of that application.
I want to get rid of the new 'Ubuntu Software.' But I cannot find its package name. Does anybody know what it is and how do I remove it?

Open the terminal and type:
When you right-click an application's icon and select Show Details, the Software app opens and shows details about that app. Of course in order to open the Software app it must be installed.
There are two different software apps in Ubuntu 20.04, Software
and Snap Store 
. The Snap Store was originally named Ubuntu Software before the first point release of Ubuntu 20.04 was released. Now it is named the Snap Store and as its name suggests it has only snap packages in it. The Software app has both snap and .deb software in it. The Snap Store and the Software app can be installed alongside each other without removing either app.
If the app with the orange shopping bag icon that was named Ubuntu Software in Ubuntu 18.04 got removed in 20.04 it can be reinstalled by running
sudo apt install gnome-software. My Ubuntu 20.04 was upgraded from Ubuntu 18.04. The old Ubuntu Software app's name was changed to Software by the upgrade and the color of the app's shopping bag icon changed from orange to light blue. Even though the name of the app has changed, the name of the app's package is still gnome-software.
