I can't use vagrant on my laptop

how did you install vagrant, and was there a local build for you too ?

I did everything the way it’s documented in my post with nix-shell -p vagrant on a newly installed NixOS, so the config wasn’t pretty vanilla too (aside from the changes mentioned in the post).

Speaking of which, do you have your configuration.nix posted somewhere? It may give some clues to folks.

On the other hand:

  • What if you tried a different channel, such as 23.11?
  • Do you get any issue when updating the system?

Other than these, I’m out of ideas for now, sorry.
