I installed the 14.04 20150630062730843 snapshot tonight (on standard dual network setup) and everything seemed to work great, until it rebooted for the 2nd/3rd time and attempted to get nvidia drivers.
I'm transcribing from a recording on my phone, so bear with me with typos...
* Staring CheckAVWizard check_avwizard
/etc/X11/xorg.conf is missing. Using video driver 'nvidia' for ....
*Installing nvidia driver this may take a few minutes . /usr/pluto/bin/nvidia-install.sh
* Starting AVWizard AVWizard_Run.sh
Then it attempts to pull the package, but fails on

Faied to fetch...
It thinks it pulled the nvidia driver and says
Nvidia driver installation requires a reboot
Please stand by while your system is rebooted
I let it do this 3 times just to make sure it wasn't a fluke.
Is there an easy way to get it to bypass the nvidia install? I really could do with a headless install, but am perfectly fine with the generic (non-nvidia) driver for what I'm using this for.
