Package: src:astropy
Version: 5.2.1-2
Severity: serious
Control: fixed -1 7.0.1-3
Tags: ftbfs bookworm

Dear maintainer:

During a rebuild of all packages in bookworm, this package failed to build.

[ Note: The bug is marked as fixed with the version in trixie/forky/sid, but
  packages in bookworm must still build in bookworm ].

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/bookworm/

About the archive rebuild: The build was made on virtual machines from AWS,
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:astropy, so that this is still
visible in the BTS web page for this package.

Thanks.
