Install a .deb from terminal in Ubuntu | Step By Step | Reconfigure and Remove a package

In this post I am going to tell you how you can install deb from terminal in Ubuntu easily.
Before we began here is what is deb...

Packages are manually installed via the dpkg command (Debian Package Management System). dpkg is the backend to commands like apt-get and aptitude, which in turn are the backend for GUI install apps like the Software Center and Synaptic.

Install deb Package:

You simply need to add the following command in the terminal

sudo dpkg -i DEB_PACKAGE

For example if the package file is called askubuntu_2.0.deb then you should do sudo dpkg -i askubuntu_2.0.deb. If dpkg reports an error due to dependency problems, you can run sudo apt-get install -f to download the missing dependencies and configure everything.




Remove a Package:

sudo dpkg -r PACKAGE_NAME

For example if the package is called askubuntu then you should do sudo dpkg -r askubuntu.

Reconfigure a Package:

sudo dpkg-reconfigure PACKAGE_NAME

This is useful when you need to reconfigure something related to said package. Some useful examples it the keyboard-configuration when you want to enable the Ctrl+Alt+Backspace in order to reset the X server, so you would the following:

sudo dpkg-reconfigure keyboard-configuration

Another great one is when you need to set the Timezone for a server or your local testing computer, so you use use the tzdata package:

sudo dpkg-reconfigure tzdata
