Hello Dhanushka, first of, I added scap-security-guide list, as that will make more sense for this kind of questions. open-scap-list is mostly about scanner issues (and in 99% cases, problem is in content, not in the scanner). Regarding the problem itself, it would be great if you took a look at the sources for the oval, maybe you'll be able to find the issue yourself. As you are on the platform. To find the source for the issue, I have checked the ID of the rule is rule_apt_sources_official. So calling this in cloned git repo: `find . | grep apt_sources_list` will tell you where are the sources: ./linux_os/guide/services/apt/apt_sources_list_official/oval/shared.xml is the source for check. There is no complexity, there just regexes, so if you find an issue, pull request with the fix would be awesome, but explanation what is the bug will also do. Thanks!
