About bluetooth i donāt understand why is important, anyway iāll do that:
wget http://ftp.us.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-iwlwifi_20190114-2_all.deb
dpkg -x firmware-iwlwifi_20190114-2_all.deb /
and now i have a terrible error:
In putty i canāt get ssh, say that pass is wrong. 
About my nuc, I use it only with proxmox, my goal is use it with some VMs, like:
Vm with Home Assistant
Vm with Pi-hole
Vm with Ubuntu test
Vm with Raspbian
Vm with Win10
In the past I have tried to install Kodi in a Vm, especially Libreelec, but was without a GPU passthrough, so 4k movies beat cpu, then I maked passthrough about gpu for the kodi vm and worked. Then there was audio problem, because was mute. Then i see the iommu groups and i discovered that audio is inside a group where is also ethernet and other stuff.
Infact when I have tried to pass also audio, i get on kodi audio, but i lost ethernet, so no internet, in kodi and also in host proxmox.The result was Kodi with audio and video, also in hdmi!, but no internet connection, no proxmox gui, no connection in other proxmox vm, a disaster, and infact if I make a frigate docker that works, maybe i can try to make also a kodi docker or lxc i donāt know, and maybe i can get a kodi that works without trouble, but this is another story and isnāt necessary for now, the priority is home assistant and frigate, that I use it for home security.
