The information is divided in three classes: states , selection states and flags. These values are intended to be changed mainly with dselect. The other files listed below are in their default directories. See option --admindir to see how to change locations of these files. Additionally, the following files are components of a binary package: control , conffiles , preinst , postinst , prerm , and postrm. Install the package. If --recursive or -R option is specified, package-file must refer to a directory instead.

Installation consists of the following steps: 1. Extract the control files of the new package. If another version of the same package was installed before the new installation, execute prerm script of the old package. Run preinst script, if provided by the package. Unpack the new files, and at the same time back up the old files, so that if something goes wrong, they can be restored. If another version of the same package was installed before the new installation, execute the postrm script of the old package.

Note that this script is executed after the preinst script of the new package, because new files are written at the same time old files are removed. Configure the package. See --configure for detailed information about how this is done. Unpack the package, but don't configure it. Configure a package that was unpacked but not yet configured.

If -a or --pending is given instead of package, all unpacked but unconfigured packages are configured. To reconfigure a package which has already been configured, try the dpkg-reconfigure command instead.

Configuring consists of the following steps: 1. Unpack the conffiles, and at the same time back up the old conffiles, so that they can be restored if something goes wrong. Run postinst script, if provided by the package.

Processes only triggers. All pending triggers are processed. If package names are supplied, only those packages' triggers are processed, exactly once each where necessary. Use of this option may leave packages in the improper triggers-awaited and triggers-pending states. This can be fixed later by running: dpkg --configure --pending.

Remove an installed package. This may avoid having to reconfigure the package if it's reinstalled later. Note: some configuration files might be unknown to dpkg because they are created and handled separately through the configuration scripts. In that case, dpkg won't remove them by itself, but the package's postrm script which is called by dpkg , has to take care of their removal during purge.

Also, the dpkg will not install the package and will leave it in an unconfigurable and broken state. This command will fix the broken package and install the required dependencies assuming they are available in the system repository.

Although you can verify the package installation by searching it through the Ubuntu dash menu. If it is available there, that verifies the package is installed.

However, the dpkg also allows you to verify the package installation. Simply type dpkg with —status or —s option to verify the package installation:. Once you no longer need an installed package, you can remove it using the dpkg command.
