I think that error is just pandas *not being built* for 3.8 yet: a 
Python version transition is ~500 binNMUs and that takes time.

dask is itself failing autopkgtests, and this is blocking pandas and 
pytest, so is a problem independently of xarray.  (The breakage was 
originally caused by pytest 4, but pandas 0.25 Build-Depends: on that.)
