How to Install Cockpit on Ubuntu 20.04

Install Cockpit on Ubuntu Server 20.04

Cockpit is a web-based server administration tool for self-managed Linux servers. The free server control panel, backed by Red Hat, is unique in the sense that the graphical interface only shows settings for installed services. It is most beneficial to install Cockpit on Ubuntu if your server is primarily used for business networking:

  • File sharing
  • LDAP integration
  • Virtual machine (VM) hosting
  • RAID storage management

Cockpit simplifies tasks for advanced users already aware of which system apps are essential to their needs.

Install Cockpit on Ubuntu

  1. SSH into your Ubuntu server.
  2. Install Cockpit:
    apt install cockpit
  3. Install a free SSL certificate for your hostname with Certbot.
  4. Cockpit requires the SSL certificate and private key to be located in the “/etc/cockpit/ws-certs.d” directory as .crt and .key files respectively. You can combine the cert and private key into a new file or copy the Certbot files separately. We’ll do the latter. Remember to replace “” with your Cockpit domain all four times:
    cp /etc/letsencrypt/live/ /etc/cockpit/ws-certs.d/ && cp /etc/letsencrypt/live/ /etc/cockpit/ws-certs.d/
  5. Make the Cockpit user the owner of the new SSL files (replacing “” within the command):
    chown cockpit-ws:cockpit-ws /etc/cockpit/ws-certs.d/ /etc/cockpit/ws-certs.d/
  6. Ensure that Cockpit will use the correct SSL (.crt) file in the “ws-certs.d” directory:
    remotectl certificate
    It should display the full path to the new cert file.
  7. Restart Cockpit to apply the SSL now:
    systemctl restart cockpit
  8. Now, create a script to ensure the Cockpit SSL files are updated automatically when Certbot renews your SSL:
    sudo nano /etc/letsencrypt/renewal-hooks/post/
  9. Add the following, replacing “” with your Cockpit hostname, to automatically update the Cockpit SSL files and restart Cockpit afterwards:
    #!/usr/bin/env bash

    echo "SSL certificates renewed"

    cp /etc/letsencrypt/live/ /etc/cockpit/ws-certs.d/
    cp /etc/letsencrypt/live/ /etc/cockpit/ws-certs.d/
    chown cockpit-ws:cockpit-ws /etc/cockpit/ws-certs.d/ /etc/cockpit/ws-certs.d/

    echo "Cockpit Restarted"
    systemctl restart cockpit
  10. Save and exit the file.
  11. Make the script executable:
    chmod +x /etc/letsencrypt/renewal-hooks/post/
  12. Test the Certbot renewal process:
    sudo certbot renew --dry-run
    You should see “Cockpit Restarted” at the end.
  13. Ensure ports 9090 and 80 are enabled in your firewall.
