Dear maintainer:

During a rebuild of all packages in unstable using the nocheck build profile,
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/202609/

A wiki page discussing how to reproduce bugs in this category and
possible solutions is available here:

https://wiki.debian.org/qa.debian.org/FTBFS/nocheck

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:emperor, so that this is still
visible in the BTS web page for this package.

Thanks.

Hi.

I know this is weird because the build log suggests that the BD to
drop its <!nocheck> would be python3-numpy , but this is actually what
my script check-nocheck told me:

==== Checking annotations for package emperor ====
Trying with all build-dependencies
Build worked
Trying without libjs-qunit
Build worked, it is ok to keep libjs-qunit <!nocheck>
Trying without python3-click
Build worked, it is ok to keep python3-click <!nocheck>
Trying without python3-notebook
Build worked, it is ok to keep python3-notebook <!nocheck>
Trying without python3-numpy
Build worked, it is ok to keep python3-numpy <!nocheck>
Trying without python3-pandas
Build worked, it is ok to keep python3-pandas <!nocheck>
Trying without python3-pytest
Build worked, it is ok to keep python3-pytest <!nocheck>
Trying without python3-skbio
Build did NOT work, python3-skbio should not have <!nocheck>
==== build-dependencies that should drop their <!nocheck> annotation ====
python3-skbio


So that's what I did.

(There may be some other solution, but not in the form of dropping
nocheck annotations).

Thanks.
