Introduction to LXD projects

Hi, I am following this on a fresh installed Ubuntu 22.04 server ( on a VM) with snap lxd 5.0.1.

Not sure if I should cross post on the main lxd forum - but I will try it here first.

When running the command:

lxc move dbserver dbserver2 --project client-website --target-project client2-website

I get this error:
Error: Migration operation failure: Unable to perform container live migration. CRIU isn´t installed.

I have then:
sudo snap set lxd criu.enable=true
sudo snap restart lxd

But no luck. I get this error:

lxc move dbserver dbserver2 --project client-website --target-project client2-website
Error: Migration operation failure: snapshot dump failed
(00.004488) Error (criu/namespaces.c:463): Can’t dump nested uts namespace for 1443
(00.004490) Error (criu/namespaces.c:724): Can’t make utsns id
(00.005484) Error (criu/util.c:641): exited, status=1
(00.006541) Error (criu/util.c:641): exited, status=1
(00.006741) Error (criu/cr-dump.c:2053): Dumping FAILED.

Not sure if it is a bug on lxd or a missing configuration that needs to be addressed on the tutorial.

Thanks in advance.
