So, it seems if you’re running a recent Ubuntu install (l/m/n/o initials) and you use Easy Install on VMWare Fusion you’ll have issues with keymaps. Up and down arrow, and a few other keys might play up too.
There’s a simple trick, run this from the console as an admin (sudo if you please):
dpkg-reconfigure console-setup
When it asks what kind of keyboard you have, hit “m” to select Macbook then hit enter. Keep hitting enter (or letter keys to select options, multiple taps on the same letter will scroll) and you’ll get your way through.
Keys should work after that 🙂
