That isn't necessarily a homekit error. Somehow it failed to install a dependency for the homekit component: pycryptodome. I'm running Hassbian myself without any issues.

Have you tried restarting Home Assistant?
Since you have a fresh install of Hassbian, it would also try the setup again (from the beginning) if a restart doesn't work. Sometimes packages doesn't install as they are supposed to.

It was a problem with the pycryptodome package. See here. It was fixed yesterday.

Thank you so much.
