+Two options
+
+1) just install Ubuntu-16 on a fresh SD card and run the install script
+
+2) run the wrong way in traffic and upgrade your existing build
+
+Part the First, Update Ubuntu via SSH (not for the faint of heart)
+These are the steps I took.  When I tried a similar set of steps on my
+dev machine they failed for all sorts of wobbly reasons.  On my "real"
+lasersaur it just worked:
+
+apt-get update
+apt-get upgrade
+apt-get dist-upgrade  # probalby not needed
+apt-get install update-manager-core
+screen -S upgrade
+#
+#  IMPORTANT:  It's possible you have too many packages installed
+#  and don't have room for the upgrader to download the next release.
+#  Be ready to apt remove a lot of stuff you can reinstall after the
+#  upgrade.  I had to remove emacs, gcc, g++, x11 (how did that get
+# installed?) then do autoclean to make room for the upgrade.
+#
+do-release-upgrade
+# now ssh in to the new port from another terminal and reattach to
+# the screen service to maintain the conneciton after the stock
+# sshd is restarted
+screen -x upgrade
+# then when it's all done:
+shutdown -r now
+
+
+Part the Second, Update driveboardapp:
+
+switch to my repo:
+https://github.com/allartburns/driveboardapp
+checkout branch "ubuntu-16"
+then re-install
+
+cd /root/driveboardapp/scripts
+./upgrade_to_driveboardapp.sh
+shutdown -r now
