Snap apps not running after updating Debian

Hi everyone. I’m a Debian testing user. Since its last update (bookworm) I’ve been unable to run snap applications. Every single time I try to run them I get the following error:

WARNING: cgroup v2 is not fully supported yet, proceeding with partial confinement
cannot change profile for the next exec call: No such file or directory
snap-update-ns failed with code 1

I can fix this by running the following command every single time I start/restart my system:

apparmor_parser -r /var/lib/snapd/apparmor/profiles/*

I want to avoid having to do this on every single boot. I found a few references to a snapd.apparmor.service service, but I’ve been unable to make it work.
First, it doesn’t seem to be installed:

systemctl enable --now snapd.apparmor.service        
Failed to enable unit: Unit file snapd.apparmor.service does not exist.

If I look for it I found it on this location:


If a copy this file into /etc/systemd/system/, create the service and try to execute it, I get:

'/usr/lib/snapd/snapd-apparmor': File not found

snapd-apparmor is on /snap/snapd/12883/usr/lib/snapd/snapd-apparmor

Any idea about how to fix this?
Thanks in advance.

An updated version of the package is already in sid: AFAIU the Debian process, the package should land in stable in a couple of days.

Here’s the bug for reference: it’s marked as grave and marked as resolved on Sep 07, so maybe the path to unstable is more complicated then I remembered.

Thanks! Will wait until the new version of snapd gets to testing.
