The archive is from RHEL8 host, but the selinux context does not display, it shows as "?", so the workflow of the following code block is messy due to the "?":

            if parts[1][0].isdigit():
                # We have to split the line again to see if this is a RHEL8
                # selinux stanza. This assumes that the context section will
                # always have at least two pieces separated by ':'.
                if ":" in line.split()[4]:
                    rest = parse_rhel8_selinux(parts[1:])
                else:
                    rest = parse_non_selinux(parts[1:])
            else:
                rest = parse_selinux(parts[1:])

It enters the parse_non_selinux function since there is no colon in the SELinux context.
