nixos-rebuild switch not working on fresh instance (ami-0e6b1f052101d5b5d) #107
Description
This is a fresh ec2 instance and nixos-rebuild switch which fails out of the box; eventually was able to get something to work (see below).
Any way to have the conventional command work out of the box?
Thank you in advance.
