Package: src:python-admesh
Version: 0.98.8-1

Dear maintainer:

I tried to build this package in buster but it failed:

--------------------------------------------------------------------------------

The build was made with "dpkg-buildpackage -B" in my autobuilder.
Most probably, it also fails here in reproducible builds:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/python-admesh.html

where you can get a full build log if you need it.

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

Thanks.
