What does incus info
show under storage_supported_drivers
? Are the commands “ceph” and “rbd” available in your PATH?
See this post for more info: Unable to migrate LXD 5.21 with microceph to Incus 6.0 - #2 by stgraber
In any case, you can always say “no” and add the ceph pool later. incus admin init
is really just a shortcut for creating an initial network, profile and storage. If the default pool uses local storage (e.g. dir / lvm / zfs) and you add a ceph pool later, you can edit the default profile so that any new containers/VMs you create use ceph by default.
