Comment 6 for bug 1780534

Since it would never (rarely?) work in a container anyway I'm not sure about the "real" need to SRU this, but fixing in 19.04 onwards seems right to me. Furthermore anyone could fix it by changing the config like
  $ echo "/usr/lib/ipsec/stroke rmix," | sudo tee /etc/apparmor.d/local/usr.lib.ipsec.stroke

Please @Andreas Dosztal - is there a real "in container" use case for this or were you just playing with it when you found the bug?
