[Debichem-devel] Bug#980050: mdtraj: FTBFS with jupyter-client 6.1.11

Source: mdtraj
Severity: normal

Dear Maintainer,

mdtraj appears to FTBFS when trying to migrate jupyter-client 6.1.6 ->
6.1.11

The failure is trying to build the example notebook examples/nmr.ipynb;
it appears to fail trying to find an external dependency (sparta) which
as far as I can tell was never installed for autopkgtests. I'm not quite
sure why this regression is visible at this point, since I can't see why
this test would have succeeded before. Presumably a change in jupyter
client affected the custom notebook executor in the testsuite.

see https://ci.debian.net/data/autopkgtest/testing/amd64/m/mdtraj/9644331/log.gz
