On a system without any file context customizations, "sepolicy gui" fails to load because it tries to read a non-existent file: FileNotFoundError: [Errno 2] No such file or directory: '/etc/selinux/refpolicy-git/contexts/files/file_contexts.local' Once this issue is fixed, another one is triggered: FileNotFoundError: [Errno 2] No such file or directory: '/etc/selinux/refpolicy-git/contexts/files/file_contexts.subs Use os.path.exists() to prevent trying to open non-existent files.
