Seems like sandbox incompatibility:

            if hit:
>               raise AssertionError('Suspicious output to stderr (matched "%s")' % hit.group(0))
E               AssertionError: Suspicious output to stderr (matched "ERROR")

test/pytest_checklogs.py:104: AssertionError
---------------------------- Captured stderr setup -----------------------------
ERROR: ld.so: object 'libsandbox.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
