The book content gets pulled in from a separate repo via an automated process. The right spot here is https://github.com/progit/progit2.

We do recommend just "apt install git" on the downloads page:

  https://git-scm.com/download/linux

though that has created occasional confusion, too (e.g., some people expect gitk).

Yeah. I think fundamentally this is a packaging issue. It looks like "git-daemon-*" has been downgraded to "Suggests" in Debian unstable. It looks like this was done in 1:2.26.0-2 last April. From the changelog:

    * debian/control: downgrade Recommends by git-all on git-daemon-run
    to Suggests. The git-all package is a "batteries included" full
    installation of Git. Automatically running a daemon is not useful
    to most of its users.

So they are already aware of and addressed the problem, but older releases will still show it.
