Previous: How To Setup Cockpit On Fedora Server
In this post, you learned that you can install all plugins of Cockpit by wildcard.sudo dnf install cockpit-*
This attempt installs the cockpit-ostree package on your Fedora Server, which does not use rpm-ostree to manage its packages. But cockpit-ostree is only intended for use on distributions that use rpm-ostree, such as Fedora Silverblue, Fedora Kinoite, Fedora IoT, Fedora CoreOS, and a small subset of RHEL that uses rpm-ostree. Your system should be using Cockpit’s PackageKit-based software updater instead.
Solution:
Just remove the cockpit-ostree package.sudo dnf remove cockpit-ostree
You don’t need to reload the Cockpit socket.
