apparmor denied something was working before
I recently installed guix binary on my Trisquel 9 machine. I am using virt-manager and qemu gives this error:

What I am really confused about is why was it blocked now? Obviously, I want to know how do I fix it. I am an apparmor newbie. I tried running aa-logprof , but it errors on no firefox profile "/etc/apparmor.d/abstractions/ubuntu-browsers.d/firefox".
