@JonoYang please review this.
These are the tests for this

• test_debian.py::DebianLSLRTest::test_DebianDirectoryIndexVisitor_from_debian
• test_debian.py::DebianLSLRTest::test_DebianDirectoryIndexVisitor_from_ubuntu

Looking good, I left a few comments.

Can you replace the ls-lR_debian and ls-lR_ubuntu files with the original ones from https://github.com/nexB/purldb/tree/main/minecode/tests/testfiles/debian/lslr, extracted from the .gz files? We want to use the same test data as before to see if we get the same expected results to ensure the fix that you created does not introduce any changes to how the function worked before. If you want, you can create an additional test with your new test ls-lR data.

@JonoYang I changed the files to the original ones but, i had to make changes to the expected.json files as there were a few errors.
Example:
all the purls in https://github.com/nexB/purldb/blob/main/minecode/tests/testfiles/debian/lslr/ls-lR_debian.gz-expected.json, are in wrong format ex: pkg:deb/debian/asterisk-mobile@1.6.2.1-1?arch=amd64.deb.

@35C4n0r The idea is to use the previous ls-lR files and then update the expected JSON results.

This test still fails: https://github.com/nexB/purldb/actions/runs/4310196055/jobs/7518392136#step:6:764

You need to do something like this:

Suggested change

	temp_gz_location = self.get_tmp_gz_file('debian/lslr/ls-lR_debian')
	test_loc = self.get_test_loc('debian/lslr/ls-lR_debian')
	temp_gz_location = self.get_tmp_gz_file(test_loc)
	with patch('requests.get') as mock_http_get:
	mock_http_get.return_value = mocked_requests_get(uri, temp_gz_location)
	uris, _, _ = debian_visitor.DebianDirectoryIndexVisitor(uri)

Thanks @JonoYang, I've updated the tests, and the original lsLr files are used, and the json result have been updated accordingly.

@35C4n0r Everything looks great! Thank you for your contribution!
