6 years ago We should probably update to a newer base image for the VM, but in the meantime you can probably work around it installing an older version of tornado - edit that script and change pip install tornado to pip install "tornado<5".
As Seb probably already told you, you're the first person to try this outside our team, so this is all valuable feedback on what doesn't work.
@tsaoyu where were we getting the raspi SD card images from? Can we get VM images from the same source?

Hi Soton team,
During the installation step on the sailing-robot wiki (https://github.com/Maritime-Robotics-Student-Society/sailing-robot/wiki/Virtual-Machine-for-Windows-Mac-users), under the Post installation setup section, where the instructions say:

So far, I have tried
pip install --user launchpadlib==1.10.2, as well as updating to Python 3.6.x, and then re-running the installation instruction, but I still get the same errors.Any help would be much appreciated. Thank you!
