Can you have a look what might go on regarding AppArmor here? Basically I don't know anything about AppArmor (or SELinux) so that I cannot help with AppArmor (or SELinux) issues. FYI: On my openSUSE Tumbleweed system where it works I do not have the actual AppArmor software installed (except libapparmor1 that is required by systemd): ------------------------------------------------------------------------ # rpm -qa | grep -i apparmor libapparmor1-2.9.1-4.1.x86_64 # rpm -e --test libapparmor1 error: Failed dependencies: libapparmor.so.1()(64bit) is needed by (installed) systemd-210-39.1.x86_64 libapparmor.so.1(APPARMOR_1.1)(64bit) is needed by (installed) systemd-210-39.1.x86_64 # rpm -q --requires systemd | grep -i apparmor libapparmor.so.1()(64bit) libapparmor.so.1(APPARMOR_1.1)(64bit) ------------------------------------------------------------------------ -- You are receiving this mail because: You are on the CC list for the bug.
