Source: flit

Hi,

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

Relevant part (hopefully):
>  fakeroot debian/rules binary
> dh binary --with python3
>    dh_testroot
>    dh_prep
>    debian/rules override_dh_auto_install
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> cp debian/build.py .
> python3 build.py
> Traceback (most recent call last):
>   File "/<<PKGBUILDDIR>>/build.py", line 19, in <module>
>     from flit_core import build_thyself
> ImportError: cannot import name 'build_thyself' from 'flit_core' (unknown location)
> make[1]: *** [debian/rules:19: override_dh_auto_install] Error 1

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.
