I’ve installed Debian 12 Bookworm recently and, as far as I could read about a fresh installation, it comes with app-armor pre-installed by default. I’m running the command aa-status as root but it’s returning: bash: aa-status: command not found. I know aa-status is part of apparmor-utils. And that’s installed too.

Being more precise, the return of apt list --installed | grep apparmor here lies in:

apparmor-profiles/stable,stable,now 3.0.8-3 all [installed]
apparmor-utils/stable,stable,now 3.0.8-3 all [installed]
apparmor/stable,now 3.0.8-3 amd64 [installed]
libapparmor1/stable,now 3.0.8-3 amd64 [installed]
python3-apparmor/stable,stable,now 3.0.8-3 all [installed,automatic]
python3-libapparmor/stable,now 3.0.8-3 amd64 [installed,automatic]

Once I “ask” systemctl about apparmor with systemctl status apparmor it “says”:

● apparmor.service - Load AppArmor profiles

I’ve also noticed the Finished apparmor.service - Load AppArmor profiles. but do not know what it mean. Do I need a profile to get it running properly? It does not come with default profiles? Could you help me to understand it better?

I was expecting the result of the aa-status command. Something like apparmor module is loaded. (like apparmor docs ). Instead I got: bash: aa-status: command not found as if it was not installed.

Thanks in advance!
