Fails install on Virtual Machine

[Anarcho]

Error occurs when running command:

nix run github:nix-community/nixos-anywhere -- --generate-hardware-config nixos-generate-config ./configurations/nixos/vm/hardware-configuration.nix --flake '.#vm' --target-host root@<ip address>

Error:

Now try logging into the machine, with: "ssh -i /tmp/tmp.Zv5bVIJelM/nixos-anywhere -o 'ConnectTimeout=10' -o 'UserKnownHostsFile=/dev/null' -o 'StrictHostKeyChecking=no' 'nixos@<IP Address>'"
and check to make sure that only the key(s) you wanted were added.

Tried with root@<ip address>

When running below command - it works.

nix run github:nix-community/nixos-anywhere/acc1651576dac4e736e05021836fd50d45f8046b -- --generate-hardware-config nixos-generate-config ./configurations/nixos/vm/hardware-configuration.nix --flake '.#vm' --target-host nixos@<IP ADDRESS>

I've ran into this same problem the whole day until finally finding this issue. In my case it's not a VM that I'm trying to target but an actual physical machine (booted into 24.05 installation media).

Using acc1651576dac4e736e05021836fd50d45f8046b does in fact seem to solve the issue.

@Anarcho Did you boot an older installer on the target host as well?

Context: The root-cause for your issue is that your nix version is too old. nix config which is used here, was introduced in nix 2.20, a bit over a year ago.

@errnoh Error message should be better, but 24.05 isn't supported upstream anymore. Please use at least a 24.11 installer.
