Cockpit is a free remote server manager that is lightweight and easy to use for GNU/Linux servers. Cockpit is a web-based graphical interface for servers intended for people new to Linux to the experts such as sysadmins. Cockpit makes Linux discoverable, allowing anyone using the software to perform tasks such as start containers, administer storage, configure networks, and inspect logs.
[Pre-Install Configuration for Cockpit]
By default, Cockpit is in the default repository. However, like most packages in the Debian stable, it soon becomes quite far behind in updates. The tutorial will install Cockpit from the Debian Bullseye Backports repository, which is often more updated than stable without getting into the testing/unstable areas.
The tutorial will also use APT Pinning, so you do not forget to get updates using the standard apt update command and not interfere with existing stable Debian 11 packages by default.
First, open the preferences file as follows:
sudo nano /etc/apt/preferences
Next, copy and paste the following.
Package: * Pin: release a=bullseye Pin-Priority: 500
Package: cockpit Pin: release a=bullseye-backports Pin-Priority: 1000
Package: * Pin: release a=bullseye-backports Pin-Priority: 100

Summary of what you added.
Backports for package cockpit is always used by default.
All packages will use Debian 11 Stable by default.
Backup will be backports if anything unavailable in stable.
Now, you will need to add either the backports to your /etc/apt/sources.list if not already present
Import Debian 11 “Bullseye” Backports:
echo "deb http://deb.debian.org/debian bullseye-backports main contrib non-free" | sudo tee -a /etc/apt/sources.list echo "deb-src http://deb.debian.org/debian bullseye-backports main contrib non-free" | sudo tee -a /etc/apt/sources.list

Update your repositories to reflect the new additions.
sudo apt update
At the current time, Cockpit on Debian 11 stable repository is at version 239.
Backports currently has version 256. Install Cockpit
Now that you have set up a newer source to install Cockpit on your Debian 11 system, execute the following command in your terminal.
sudo apt install cockpit
How to Install Cockpit on Debian 11 Bullseye
Once installed, by default, the service is not active, so you will need to do a few systemctl commands as follows.
To start Cockpit:
sudo systemctl start cockpit.socket
To enable Cockpit on system startup:
sudo systemctl enable cockpit.socket
Next, verify the status of Cockpit to make sure it is running correctly on your system:

- How to access Cockpit Web Interface
Open any web browser of a system that can access the IP address of the Debian 10 or 11 Server where you have installed the Cockpit web console. In URL box type-
You will get a warning of HTTPS error, here click on the Advanced button and then Procced/Continue unsafe link.
- Login
Use the username and password of the user available on your Debian server to access the Web console Dashboard.
- Install Container to use Docker images on CockPit
Error: package cockpit docker has no installation candidate if you try to install it using APT.
Now, those who are interested in running containers on Debian 11 or 10 but using the Cockpit web interface can install Podman because Docker is not available for it. However, don’t worry Podman is exactly the same and also its command line works like Docker CE. Hence, use the given command:
sudo apt install cockpit-podman
- Create Podman Cockpit Containers: Error: Unable to search for images.
Now, to create containers using Podman on Cockpit, click on the option given for the same on the left side menu. After that, click on the Start button (given in notification).
To pull any Docker Image from its library to create Containers, click on the “Get Images” button. There Enter the name of the image you want to pull. For example – ubuntu.
However, in our case the Podman was unable to pull images, it is because the library path for Docker images has not been declared in the Debian Podman configuration file. Hence, go to your server command terminal or directly access it from the Cockpit to edit the configuration file.
sudo nano /etc/containers/registries.conf
Scroll to the end of the file and copy-paste the following lines:
[registries.search] registries = ['docker.io', 'registry.fedoraproject.org', 'quay.io', 'registry.access.redhat.com', 'registry.centos.org']
Save the file by pressing CTRL+O and then hit the Enter key. To exit the same use Ctrl+X.
Restart Podman:
sudo systemctl restart podman
Now, go to Cockpit Podman, hit the Get Image
Get Docker Image Debian 11 Cockpit
Search for docker Images Podman Container debian Start Container
In this way, we can install Cockpit on Debian 11 or 10 using the command line to manage the Server’s Applications, Services, Software Updates, and more remotely.
- How to update Cockpit
