Hi all, I've noticed two consistent test failures in GNU Guix's diffoscope when building using OpenSSH 9.8p1. Here's the failures: ``` =================================== FAILURES =================================== __________________________________ test_diff ___________________________________ differences = [] @skip_unless_tool_is_at_least("ssh-keygen", openssh_version, "6.9") def test_diff(differences): expected_diff = get_data("openssh_pub_key_expected_diff") > assert differences[0].unified_diff == expected_diff E IndexError: list index out of range tests/comparators/test_openssh_pub_key.py:60: IndexError __________________________ test_compare_non_existing ___________________________ monkeypatch = <_pytest.monkeypatch.MonkeyPatch object at 0x7fffefa9c700> opensshpubkey1 = <<class 'abc.PublicKeyFile'> /tmp/guix-build-diffoscope-269.drv-0/source/tests/data/test_openssh_pub_key1.pub> @skip_unless_tools_exist("ssh-keygen") def test_compare_non_existing(monkeypatch, opensshpubkey1): monkeypatch.setattr(Config(), "new_file", True) difference = opensshpubkey1.compare( MissingFile("/nonexisting", opensshpubkey1) ) assert difference.source2 == "/nonexisting" > assert len(difference.details) > 0 E assert 0 > 0 E + where 0 = len([]) E + where [] = <Difference /tmp/guix-build-diffoscope-269.drv-0/source/tests/data/test_openssh_pub_key1.pub -- /nonexisting []>.details tests/comparators/test_openssh_pub_key.py:70: AssertionError ``` It's possible this is a GNU Guix issue (opened [here](https://issues.guix.gnu.org/71886)), although I would be surprised as the breaking commit `6522f93ed0` only upgraded OpenSSH from `9.7p1` to `9.8p1`. The issue also occurs in diffoscope 271.
