The Ubuntu mainline kernel build unfortunately currently does not have apparmor set as the default LSM. This is due to some config changes done when adding the LSM stacking patches (Ubuntu tries to keep the configs as close as possible). Addressing this is wip and should land with the next revision of the LSM stacking patches
until then you can enable apparmor by editing the grub kernel command line by adding security=apparmor -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1737005 Title: Mainline kernel 4.14 does not start apparmor Status in linux package in Ubuntu: Incomplete Bug description: With Ubuntu 16.04.3 LTS (Xenial Xerus), and Ubuntu mainline kernel 4.14.3 or 4.14.4 systemd fails allways starting apparmor.service and ureadahead.service.
