When you try to install Guest Additions in Ubuntu 9.04 alpha6 . After executing the installer

sudo sh ./VBoxLinuxAdditions-x86.run x11

You might see similar to the following error

Warning: unknown version of the X Window System installed. Not installing
X Window System drivers.

One possible explanation to this is that the 2.1.4 vbox video drivers do not yet support Xorg version which ships with Alpha 6.

Work around for this problem

Mount the VirtualBox Guest Additions CD. You can do this from Devices > Install Guest Additions

Applications > Accessories > Terminal and enter the following command to enter in to you cdrom

$cd /media/cdrom/

Extract the the installer

sudo ./VBoxLinuxAdditions-x86/amd46.run --target /vbox

Note:- Select your hardware architecture file to extract i.e x86/amd64 and vbox is sample directory you can choose where ever you want to extract.

Now you need to edit the install.sh file (Inthis case i am in vbox directory)

sudo gedit install.sh

In Line 415 change

1.5.99.* | 1.6 )

to

1.5.99.* | 1.6.0 )

Save and exit the file

Note:- This is needed, because the version that is returned by X -version is 1.6.0, not 1.6.

Now run your installer using the following command

sudo ./install.sh

After completing installation Reboot your system.

That's it enjoy your virtualbox

    Dude I just did your step by step and I had to change this line to
    sudo ./VBoxLinuxAdditions-x86/amd46.run –target /vbox
    Where I put a space in between target and /vbox. I honestly don’t know why I had to do that but thats what worked for me. I then went through the rest of your installation without a hitch. I installed Linux Mint 7 Gloria on Ubuntu 9.04 host with vbox
