Same here. Looks like maiden was not getting started properly.
I think the symlink for it in /home/we/ got removed in the update?
I did the following (after first checking to see if ‘maiden’ was in fact not in my home directory)
cd ~ ln -s ~/go/src/github.com/monome/maiden
EDIT: (NOTE - I’m running on Raspberry Pi so I don’t know if this path is the same for Norns hardware)
