    Cool tip, all that we need and without mumble

    Just tried today with 4.3.26 and it did not work. The development tools installed fine, but the VBoxLinuxAdditions.run failed.

    Mr Gaggl,

    Thanks, needed this.

    Thanks, work great. You have to insert one line:

    after:
    sudo mount /dev/cdrom /media/cdrom/

    this:
    cd /media/cdrom

    Greetings Frank

    My CentOS 7 server with no UI wouldn’t auto-mount the CD, so I had to do that manually:

    $ sudo su –
    # mount /dev/sr0 /mnt
    # cd /mnt
    # ./VBoxLinuxAdditions.run

    Umounting is unnecessary because you want to reboot after installation anyway …

    I tried all the possibilities above and still can not proceed with the installation. Can someone please help me? I tried to mount the CD manually as @bundklicker said but with no efforts too. In this case I get the message: no medium fun on /dev/sr0
