Ubuntu 23.10 snapcraft plugin dotnet cannot find build-package 'dotnet-sdk-8.0'

I tried launch after this

multipass launch core18

and this

multipass delete --all
multipass purge

It writes

launch failed: KVM support is not enabled on this machine. Please ensure the following:
1.	The system’s CPU supports virtualization.
2.	Virtualization is enabled in the system BIOS.
3.	The KVM kernel modules are loaded.

Ill try in the evening to do it on wsl-2 and write resutls. Probably inside wsl-2 it will recognize virtualization.
