Hi,
json-tricks currently is blocked from migration to testing, see
#1101381. This is because its autopkgtests fail on s390x. Indeed,
trying a build of json-tricks on s390x also shows a FTBFS.
The embedded data in test_np.py assumes the tests are running on
systems where the native arch is little-endian. Obviously thats
wrong on s390x.
Just to reiterate, the test failures are as follows:

Attached is a patch that can be dropped into debian/patches, which fixes the
FTBFS on s390x. TBH I have not tested the patch on non-s390x, but I assume
it should be fine on little-endian archs.
There are probably other ways of fixing this, but adding "endian":
"little" to the test data seems straightforward.
Best,
Chris
From: Chris Hofstaedtler <z...@debian.org>
Test data assumes tests are running on little-endian systems, or at least
that the native endianness is little. Obviously this breaks on big-endian
systems like s390x. Make the assumption explicit by adding "endian": "little"
to the to-decoded test-data.
Fixes FTBFS and CI test failures on s390x.
