gdebi is one of the best ways to install deb files on Ubuntu Linux. I prefer this system because it collects all dependencies before installing the main .deb file and because gdebi will try to remove dependency errors while performing an installation.
Before you go installing the deb file, it is best to install gdebi onto your system. Gdebi is available for both the Terminal/Shell and GUI – Graphical User Interface ways. By installing through gdebi, it will be more efficient and faster compared to the Ubuntu software center.
sudo apt install gdebi-core
sudo gdebi dialogware_amd64.deb
There is another way to install deb files on the Ubuntu system, which is an apt-get tool.
sudo apt install ./dialogware_amd64.deb
If your Ubuntu system is old enough, you’ll need to move the deb file into it. The above command will download any dependencies required when running in the Terminal.
or check it:
sudo dpkg -i dialogware_amd64.deb
