port install error "checksum does not exist" : clean and reinstall

I had an error with the Mac Ports (https://www.macports.org/) on the dbus-glib install while trying to install some other packages. It was just saying that it did not exist in /opt/local/var/macports/distfiles/dbus-glib . It's not clear what broke this package for now, but the way to solve the issue was simple as found here : https://trac.macports.org/ticket/45534


        sudo port clean


and then, reinstall...
        sudo port install


And check, I could upgrade all the other packages and install some other new ones :-)
