Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.

Relevant part (hopefully):
http://qa-logs.debian.net/2021/01/20/octave-symbolic_2.9.0-3_unstable.log

A list of current common problems and possible solutions is available at
http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute!

If you reassign this bug to another package, please marking 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 me
so that we can identify if something relevant changed in the meantime.

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.

We believe that the bug you reported is fixed in the latest version of
sympy, 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 980707@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
