Ubuntu – Ubuntu Server minimal package


What is the best why to install an Ubuntu Server image with the minimum possible of package ( no default, no extrat ) that can only allow ssh connection to it and nothing else.

Best Answer

  • Perhaps the Ubuntu "Minimal CD", aka the "minimal ISO image", is close enough to what you are looking for.

    After doing a minimal install, I think there's only one more thing you need to do to allow ssh connection:

    The Ubuntu Server Guide says (in the OpenSSH Server section) that

    sudo apt-get install openssh-server

    allows people to ssh to your server. You'll probably also want to to the other things suggested at How do I configure a new Ubuntu installation to accept ssh connections? .


    If on one machine one installs the "Minimal CD", and then runs

    sudo tasksel install server

    and on another machine one installs the "Ubuntu Server CD", my understanding is that the two machines are practically the same.

    If you know what the difference is between them, please post that difference to Is using Ubuntu Minimal any different from Server? .
