Weird. I tried it repeatedly at my work machine, both using gbp and debuild
(but didn't try building in a chroot), and it failed several times.

I tried today from my home computer, and it (reliably) passes this point no
issues.

The package fails to build because of four test failures, but that's a
completely different issue 😉

Failures:
   1) Fugit::Cron#previous_time succeeds "21 0 * * 1%2 America/Sao_Paulo" 2024-03-13 12:00 -> "2024-03-04 04:21:00" in Europe/Paris
      Failure/Error:

          "too many loops for #{@original.inspect} #previous_time, breaking, " +
          "cron expression most likely invalid (Feb 30th like?), " +
          "please fill an issue at https://git.io/fjJCQ"
        ) if (i += 1) > MAX_ITERATION_COUNT
