How do I update software that I installed with a downloaded .deb file in ubuntu software center?

When I open the downloaded file in software center I can only choose to remove the software and install it again. That works, but is this the way to go?

    Indeed, there is no standard procedure for updating software installed directly from a .deb file, which is why you should prefer installing software from repositories (including ppas) or self contained packages with update functionality (snap or flatpak).

    In this case, I use gdebi to install it from the new .deb and it writes over the existing install. So far, so good. I only do this with a couple of pieces of software, however.

I used the command line : sudo dpkg -i and the downloaded deb file name.
The output confirms it's installing a new version over the current one.

$ sudo dpkg -i file.deb 
[sudo] password for user:
