  1. So I’m curious how this differs from Webmin or I’d go even as far to say as this is GUI implementation of anisble/puppet or the like.

    • @c4ifford

      There is no much difference, the underlying system administration functionalities are more like the same. Only that Webmin offers several other functionalities compared to Cockpit.

  2. I tried install this tool and i have a problem:
    sudo apt-key adv –keyserver –recv-keys F1BAA57C – done
    sudo apt-get update – done

    root:~# apt-get install cockpit
    Reading package lists… Done
    Building dependency tree
    Reading state information… Done
    Some packages could not be installed. This may mean that you have
    requested an impossible situation or if you are using the unstable
    distribution that some required packages have not yet been created
    or been moved out of Incoming.
    The following information may help to resolve the situation:

    The following packages have unmet dependencies:
    cockpit : Depends: cockpit-bridge (>= 129-0~unstable) but it is not going to be installed
    Depends: cockpit-bridge (= 129-0~unstable) but it is not going to be installed
    Depends: cockpit-dashboard (= 129-0~unstable) but it is not going to be installed
    Depends: cockpit-ws (< 129-0~unstable.1~) but it is not going to be installed
    Depends: cockpit-system (= 129-0~unstable) but it is not going to be installed
    Recommends: cockpit-docker (= 129-0~unstable) but it is not going to be installed
    Recommends: cockpit-storaged (= 129-0~unstable) but it is not going to be installed
    Recommends: cockpit-networkmanager (= 129-0~unstable) but it is not going to be installed
    E: Unable to correct problems, you have held broken packages.

  3. Fantastic tool!
    Small typo in Ubuntu installation:
    Wrong: sudo systemctl enable –now cockpit.sock
    Correct: sudo systemctl enable –now cockpit.socket

    • @mightyme

      I can not exactly tell, if you installed it already, you can see that it offers a centralized interface to access several servers but each server with its own terminal. And the commands you run only apply to a particular server unless you write scripts to achieve patch management or single command to update several servers at once.

      It is only in the graphs where info from different servers is merged.However, you can ask the developers: of cockpit for more information on that. In case it can not be done, try to make a suggestion for possible future additions.

  4. Hi Aaron. The command for Arch is wrong (or mistyped). The command should be:

    # yaourt -S cockpit 
    # yaourt cockpit

    Thanks for the great article!
