[Debian-astro-maintainers] Bug#1127111: astroquery: will FTBFS during forky support period

Fri Feb 6 12:02:10 GMT 2026 

Package: src:astroquery
Version: 0.4.11+dfsg-5
Severity: important
Tags: ftbfs forky sid
User: debian-qa at lists.debian.org
Usertags: ftbfs-during-forky-support-period

Dear maintainer:

During a rebuild of all packages in unstable with the system clock set
at 2030-08-09 (estimated to be three years after the release date of forky),
this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/ftbfs-future/

About the archive rebuild: This is an effort to keep forky free from
FTBFS bugs during its lifetime as a supported distribution, as
explained here for trixie:

https://lists.debian.org/debian-devel/2024/05/msg00414.html

This category of bugs is considered to be RC for forky, but I will
wait two months from now before raising to serious to give people a
little bit more time to fix them.

The build was made using sbuild and a reduced chroot with only
build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:astroquery, so that this is still
visible in the BTS web page for this package.

Thanks.
