[Bas Couwenberg]

Source: python-xarray
Version: 0.15.0-1
Severity: serious
Justification: makes the package in question unusable or mostly so
Control: tags -1 ftbfs

Dear Maintainer,

While doing a test rebuild to triage #950743 your package FTBFS:

 building [html]: targets for 36 source files that are out of date

 Notebook error:
 NoSuchKernel in examples/ERA5-GRIB-example.ipynb:
 No such kernel named python3
 make[2]: *** [Makefile:57: html] Error 2
 make[2]: Leaving directory '/build/python-xarray-0.15.0/doc'

You can see the same in the reproducible builds logs:

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

There is no buildlog on the buildd for this version which suggests that it was not built there.

The git repo has also not been updated with the changes for 0.15.0-1.

Kind Regards,

Bas
