Hello,
indeed most of them fail. I attached a text file with the output of the
failed tests. If a test is not included in the text file it is because
it didn't throw any errors.
I tried them on the system in question, another updated system and out
of curiosity on two opensuse systems, the results were the same. Is
there another prerequisite to running these tests?
Greetings
