Update software with .deb file

Question

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?

Answer 1

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
