How to install Ubuntu under Deb Package

Deb is the Debian Linus installation format, similar to Red Hat rpm, the main installation command is:dpkg-i file.deb

Dpkg is a shorthand for the Debian package, a suite management system specifically developed for Debian, which facilitates the installation, updating and removal of software. All Linux distributions originating from Debian use dpkg, such as Ubuntu, Knoppix, and so on.
Here are some common ways to use Dpkg:

1. Dpkg-i <package.deb>
Install a Debian package, such as files you have manually downloaded.

2. Dpkg-c <package.deb>
List the contents of <package.deb>.

3. Dpkg-i <package.deb>
Extract package information from <package.deb>.

4. Dpkg-r <package>
Remove a package that has already been installed.

5. Dpkg-p <package>
Completely clears an installed package. Unlike remove, remove simply deletes the data and the executable file, purge also removes all the configuration files.

6. Dpkg-l <package>
List all files for <package> installation. At the same time, look at dpkg-c to check the contents of a. deb file.

7. Dpkg-s <package>
Displays information about the packages that have been installed. At the same time, see Apt-cache displays the package information in the Debian archive, as well as dpkg-i to display the package information extracted from a. deb file.

8. Dpkg-reconfigure <package>
Once again, a package has been installed, assuming it is using debconf (debconf provides a unified configuration interface for package installation).
