Ok, I think we got it. In your system, /etc/os-release must be a file, and not a symlink as it is in our ubuntu systems:
$ ll /etc/os-release lrwxrwxrwx 1 root root 21 jan 2 14:25 /etc/os-release -> ../usr/lib/os-release $ ll /usr/lib/os-release -rw-r--r-- 1 root root 393 jan 2 14:25 /usr/lib/os-release Our profiles have a rule to allow /usr/lib/os-release (via globbing), but not /etc/os-release specifically. ** Changed in: ubuntu-advantage-tools (Ubuntu) Status: New => Confirmed ** Changed in: ubuntu-advantage-tools (Ubuntu) Assignee: (unassigned) => Andreas Hasenack (ahasenack) ** Changed in: ubuntu-advantage-tools (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065573 Title: esm-cache.service denied access to /etc/os-release by apparmor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-advantage-tools/+bug/2065573/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
