I'm facing a small problem with my MYSQL in Linux Mint. When I try to initialize the service, APPARMOR denies the permission, it follows the logs:

Would anyone know what it could be? In my lay vision, APPARMOR is denying read access, I have already looked at various forums and no solution has helped me.
