While trying to build and run a project, ubuntu-sdk says:
Starting /usr/bin/autopilot3-sandbox-run... E: Xephyr executable not found. Please install Xephyr /usr/bin/autopilot3-sandbox-run exited with code 1
I can't find that package on the repositories. Any ideas on how to solve this?
You need to install the Xephyr X server for the emulator.
