Can't change group access. Password not reconized in Terminal

Asked by wingerx5

I am trying to install Sun virtual box on Ubuntu Karmic Kuala. I got to the point where I'm supposed to install XP. I received an error message, “failed to start the virtual machine windows XP SP3 32-bit.
Cannot open the host device'/dev/fd0' for read/write access. Check the permissions of that device('bin/ls -l /dev/fd0'): most probably you need to be a member of the device group. Make sure that you log out/login after changing the group settings of the current user (VERR_ACCESS_DENIED).”

I checked the groups. As far as I can tell the group for that device is "floppy". I thought I could use the command 'chmon' to add myself to the group, however when I went to the terminal and entered" the command 'su' and my password I received a message Authentication Failure." I tried several times. I know it is the correct password as it works in other instances.

My knowledge of Linux is very limited and I've ran out of ideas.

The root account is disabled in Ubuntu, so you cannot log into it using su. You need to prefix the command with sudo.

Although if you're not using the floppy drive in your guest machine you could disable it in the settings.
