After installing the driver for the network ar8152
card (Thanks Tyson), I was able to install 12.04 via the update
manager in a mere 4 hours. I then had to spend another hour getting
networking working in 12.04. After that It took about two hours to get
groovy turtlebot-desktop up. There was a problem with rosdep, but the pip
install of wstool, rosdep, etc. held me up. Still need some tuning on the
network, if you enable wireless, the wired connection gets hosed. So after
about 8 hours, I can run roscore. ROS is not for sissies.
I hope to test the new version on the Willie base
tomorrow.
