To uninstall a deb package on an Ubuntu Linux system, you can use the dpkg command with the --purge option.
Here is an example of how to uninstall a deb package on an Ubuntu system:
Open a terminal window on the Ubuntu system.
Use the dpkg command with the --purge option and the name of the deb package to uninstall the package. For example:
sudo dpkg --purge package_name
Replace package_name with the name of the deb package that you want to uninstall.
If the deb package has any dependencies, the dpkg command will display a message asking if you want to remove the dependencies as well. To remove the dependencies, type y and press Enter.
The dpkg command will uninstall the deb package and any dependencies, and remove them from the system.
After following these steps, the deb package and any dependencies should be removed from the Ubuntu system.
Keep in mind that the dpkg command does not remove the configuration files for the deb package. If you want to completely remove the deb package and all its configuration files, you can use the apt-get command with the --purge option instead of the dpkg command.
