As you may know, Canonical has decided to adopt the GNOME Ubuntu Software Center as the default graphical package manager in the Ubuntu 16.04 LTS Xenial Xerus operating system, replacing the old Ubuntu Software Center. Canonical has also renamed the GNOME application to Ubuntu Software.
However, the new application did not allow installations of .deb packages downloaded from the Web.
For those who don't know, the application allows an easy way to install packages, since all it takes is a double-click on the .deb installation.
Of course, there was always the option of installing .deb packages from third-party vendors via the command line (e.g. sudo dpkg -i package_name.deb) or using another graphical package installer, such as Gdebi, which can be installed from the software repositories.
However, it appears that Canonical has released a patched version of GNOME Software to the main software repositories for users who have installed the stable version of the operating system.
This way you can update to the new Ubuntu Software which allows installing debs from third parties.
