Flatpak Unable to register authentication agent

Posted on

PolicyKit1 was not provided by any .service files

In this article I share how to fix the Unable to register authentication agent Authorization error when installing a flatpak application.

When I install the flatpak application, the error that appears is:

** (flatpak install:27692): WARNING **: 00:09:57.214: Unable to register authentication agent: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.PolicyKit1 was not provided by any .service files
The remote ‘flathub’, referred to by ‘org.kde.kdenlive’ at location https://dl.flathub.org/repo/ contains additional applications.
Should the remote be kept for future installations? [Y/n]: Y
error: Authorization error: The name org.freedesktop.PolicyKit1 was not provided by any .service files

Flatpak Unable to register authentication agent

How to fix this?

The way to fix this is to install “policykit-1” using the command:

sudo apt install policykit-1

Then policykit-1 will be installed:
