How to install .deb file on ubuntu
The following passage is based on the Ubuntu Official Website
Actually the .deb file is meaning Debian Package because ubuntu is based on Debian OS.
There are two ways for you to install Debian Package.The First way is rather simple that what you should do is just to doucle-click the package,then a package installer will show up,click the “install package” button.If you have a missing dependency,it will inform you of that.Don’t worry about it ,just download the new version available from the respositories!
Another way to install a Debian package is to use the command line,just like this:
sudo dpkg -i *.deb
