Hi,

This package fails to build a source package after a successful build
(dpkg-buildpackage ; dpkg-buildpackage -S).

This is probably a clear violation of Debian Policy section 4.9 (clean target),
but this is filed as severity:minor for now, because a discussion on
debian-devel showed that we might want to revisit the requirement of a working
'clean' target.

More information about this class of issues, included common problems and
solutions, is available at
https://wiki.debian.org/qa.debian.org/FTBFS/SourceAfterBuild

Relevant part of the build log:
The full build log is available from:
http://qa-logs.debian.net/2023/08/13/jupyter-notebook_6.4.12-2.2_unstable.log

If you reassign this bug to another package, please mark it as 'affects'-ing
this package. See https://www.debian.org/Bugs/server-control#affects

If you fail to reproduce this, please provide a build log and diff it with mine
so that we can identify if something relevant changed in the meantime.

We believe that the bug you reported is fixed in the latest version of
jupyter-notebook, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1048015@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
