How can i install .deb package that i built?

I'm new at Ubuntu. I built my program as .deb (There were two scripts). I couldn't open it. I installed it from Ubuntu Software because I don't know how to install via terminal. It doesn't seem to be a program in my computer. So, what should I do?

I tried to run my package with "dpkg -i" like below:

(Reading database ... 204097 files and directories currently installed.)
Preparing to unpack py2executable_v0.1_amd64.deb ...
Unpacking py2executable (0.1) over (0.1) ...
Setting up py2executable (0.1) ...

1. .deb installation packages can be installed with the apt tool as

    sudo apt install path/to/the/file.deb

   This automatically will pull in required dependencies. Since you know how to prepare .deb packages, you will probably know that, for your package to be installable, the dependencies you require should mach these provided by the base system of the particular Ubuntu version for which you make the package.

2. Another way to install .deb packages is the lower-level tool dpkg -, followed by a sudo apt-get install -f to fix missing dependencies if any:

   sudo dpkg -i path/to/the/file.deb
   sudo apt-get install -f

3. A simple graphical tool to install .deb packages is gdebi, available in the software sources.
