Public bug reported: Several critical systems are broken with the default Ubuntu 17.10 apparmor profile when booting in kernel 4.14, eg DHCP/networking and mysql-server.
I got it working by applying the attached patch from the /etc directory. The patch is mostly based on the patch provided in comment #34 in the upstream bug at https://bugs.debian.org/cgi- bin/bugreport.cgi?bug=877581. I had to remove the sections for the files that Ubuntu doesn't have (such as tor, tor.browser, haveged and libvirt) and to get DHCP to work, I also had to add 'w' permission to /usr/lib/NetworkManager/nm-dhcp-helper to avoid this syslog message: apparmor="DENIED" operation="create" profile="/usr/lib/NetworkManager /nm-dhcp-helper" pid=3876 comm="nm-dhcp-helper" family="unix" sock_type="stream" protocol=0 requested_mask="create" denied_mask="create" ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: apparmor 2.11.0-2ubuntu17 ProcVersionSignature: Error: [Errno 2] No such file or directory: '/proc/version_signature' Uname: Linux 4.14.0-rc5-generic x86_64 ApportVersion: 2.20.7-0ubuntu3 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Wed Oct 18 12:59:38 2017 InstallationDate: Installed on 2017-08-16 (62 days ago) InstallationMedia: Ubuntu 17.04 "Zesty Zapus" - Release amd64 (20170412) JournalErrors: Error: command ['journalctl', '-b', '--priority=warning', '--lines=1000'] failed with exit code 1: Hint: You are currently not seeing messages from other users and the system.
