[Lucas Nussbaum]

Source: python-xarray
Version: 0.15.1-1
Severity: serious

Hi,

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

Relevant part (hopefully):
> make[2]: Entering directory '/<<PKGBUILDDIR>>/doc'
> sphinx3-build -b html -d _build/doctrees   . _build/html
> Traceback (most recent call last):
>   File "/<<PKGBUILDDIR>>/debian/sphinx3-build", line 11, in <module>
>     from sphinx import main, make_main
> ImportError: cannot import name 'main' from 'sphinx' (/usr/lib/python3/dist-packages/sphinx/__init__.py)
> make[2]: *** [Makefile:57: html] 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.
