Comment 2 for bug 2038567

Current suspects are out of date apparmor features in livecd-rootfs pending https://launchpad.net/ubuntu/+source/livecd-rootfs/23.10.55

kernel, apparmor, snapd, lxd, snapd again having fits about all of them because of:

......................................................................
Make snap "snapd" (20092) available to the system

2023-10-05T19:04:57Z INFO Requested daemon restart (snapd snap).

......................................................................
Copy snap "lxd" data

2023-10-05T19:04:56Z ERROR unlinkat /var/snap/lxd/common/var/lib/lxcfs/proc/cpuinfo: function not implemented

......................................................................
Run install hook of "lxd" snap if present

2023-10-05T19:04:55Z ERROR run hook "install": cannot read mount namespace identifier of pid 1: Permission denied

and also because of:

Oct 05 19:21:39 mantic-con-priv snapd[2338]: taskrunner.go:299: [change 7 "Setup snap \"snapd\" (20092) security profiles" task] failed: cannot reload udev rules: exit status 1

Oct 05 19:21:39 mantic-con-priv (sd-gens)[2568]: Read-only bind remount failed, ignoring: Permission denied

and because of:
