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
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.
