We've just released sbx 0.32.0:
https://github.com/docker/sbx-releases/releases/tag/v0.32.0
Notably, that fixes running sbx on headless Linux, and also brings support for our v2 kits format (check out https://github.com/docker/sbx-kits-contrib for kits examples).
Also, much better performance when using the new `--clone` flow thanks to enabling virtiofs caching.
