Software Center cannot be reinstalled

I'm using Ubuntu 18.04.2.

I cannot find Ubuntu Software (or Software center) in my dash. I have tried to install it with the following commands:

sudo apt-get update
sudo apt-get upgrade

then

sudo apt-get install software-center*

After all the processes have run I get the following message:

$ sudo apt-get install software-center
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package software-center is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'software-center' has no installation candidate

I think the problem might be related to my earlier attempt to install the MATE desktop environment. Since it failed I purged the installed packages. I assume that when I purged MATE packages I also deleted the software center and something that is needed its re-installation.

Solution 1:

The package software-center does not exist in 18.04, use gnome-software instead.

sudo apt install gnome-software
