Hello,
I tried to make a VM today with uvtool, and I hit this.
$ uvt-kvm create --cpu 4 --memory 4096 --disk 10 noble-test release=noble
arch=amd64

RuntimeError: Could not create any key
uvtool places its ssh keys in /tmp/uvt-kvm.sshtmp<random>/algorithm, so
this is outside .ssh.
I think we need to relax this change as it seems to affect quite a few
packages.
