## Package Updates

Cockpit uses the PackageKit D-Bus API to get information about available package updates and to apply them, in an Operating System independent manner.

To perform similar tasks from the command line, use the pkcon command:

    $ pkcon refresh

    $ pkcon get-updates
    Available  sudo-1.8.20p2-1.fc26.x86_64 (updates-testing)
        Allows restricted root access for specified users
    Available  vim-filesystem-2:8.0.617-1.fc26.x86_64 (updates-testing)
        VIM filesystem layout
    Available  vim-minimal-2:8.0.617-1.fc26.x86_64 (updates-testing)
        A minimal version of the VIM editor

    $ pkcon get-update-detail sudo
    Details about the update:6.x86_64 [fedora]
     Package: sudo-1.8.20p2-1.fc26.x86_64
     Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1452941
     Update text: - update to 1.8.20p2
        - added sudo package to dnf/yum protected packages

    $ pkcon update
    The following packages have to be updated:
     sudo-1.8.20p2-1.fc26.x86_64	Allows restricted root access for specified users
     vim-filesystem-2:8.0.617-1.fc26.x86_64	VIM filesystem layout
     vim-minimal-2:8.0.617-1.fc26.x86_64	A minimal version of the VIM editor
    Proceed with changes? [N/y] y
    [...]

Of course you can also use your Operating System specific commands for that, such as dnf updateinfo info on Fedora or sudo apt upgrade on Debian.
