I upgraded my Linux Ubuntu to Ubuntu 18.04 and Software Center seems to be missing. I tried to install from Command line. But I endup with the following Error.
> user@user-HP-ProBook-450-G2:~$ sudo apt-get install software-center > [sudo] password for user: 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 > user@user-HP-ProBook-450-G2:~$ ^C user@user-HP-ProBook-450-G2:~$
