Dear maintainer,

I see that the package astro-education (version 5.0) suggests lightspeed
which is not in unstable.

This can be seen in https://packages.debian.org/unstable/astro-education
. Search for "Package not available".

The missing package used to be in Debian but they were removed some time
ago:

- https://tracker.debian.org/pkg/lightspeed

Should it be dropped or changed?

Thank you,
