If you want to run VMs in Incus, you need to install a newer version of qemu from backports as well:

sudo apt install incus/bookworm-backports qemu-system-x86/bookworm-backports qemu-system-common/bookworm-backports qemu-system-data/bookworm-backports seabios/bookworm-backports

However, if you only care to run containers in Incus, you can install just incus-base:

sudo apt install incus-base/bookworm-backports

Thank you

Alternatively and shorter:

sudo apt install -t bookworm-backports incus
