Docker Tunnel error

I’m trying to do a “forge tunnel -d” but I just get the following error.

Checking Docker image... 100%   
Your Docker image is up to date.
docker: Error response from daemon: AppArmor enabled on system but the docker-default profile could not be loaded: running `/usr/sbin/apparmor_parser apparmor_parser -Kr /var/lib/docker/tmp/docker-default990416561` failed with output: AppArmor parser error for /var/lib/docker/tmp/docker-default990416561 in /etc/apparmor.d/tunables/kernelvars at line 16: syntax error, unexpected TOK_SET_VAR, expecting TOK_END_OF_RULE

First I’ve tried to run this in a while. Any ideas?

Does anyone at Atlassian know what is causing this?

Found the issue. There is a problem with mysql server database. I uninstalled that, re-installed apparmor and it all worked. Apparmor doesn’t use mysql server so I don’t know what the hell is going on there.
