installer failed due to networking issue

[rapenne-s]

I had connectivity issues during the installation process, this leaves the installer in a weird state, and I couldn't resume / uninstall it.

The following actions will be taken:
* Create the directory `/nix`

* Fetch Nix from `https://releases.nixos.org/nix/nix-2.11.0/nix-2.11.0-x86_64-linux.tar.xz`

* Create build users and group

* Create a directory tree in `/nix`

* Move the downloaded Nix into `/nix`

* Setup the default Nix profile

* Configure Nix daemon related settings with systemd

* Place the nix configuration in `/etc/nix/nix.conf`

* Place channel configuration at `/root/.nix-channels`

* Configure the shell profiles

* Start the systemd Nix service and socket

Are you sure? (y/N): Cancelled!Okay, didn't do anything! Bye!

[Hoverbear]

It looks like you cancelled the revert (hello #24 ) which is why it failed to uninstall.

Did you attempt an uninstall after the fact?

[rapenne-s]

Oh, I certainly pressed 'y + ENTER' at the first input. Did it reuse the second key for the next question? 🤔 that would explain this behavior

[Hoverbear]

I think it did reuse it, I caught that too. I'm looking forward to getting that prompt fixed.

[Hoverbear]

Originally I thought it wouldn't reuse it since we create a new event stream each time... https://github.com/DeterminateSystems/harmonic/blob/64e7423a0a1a08a7b500095429fe2dea4c630a10/src/interaction.rs#L7-L51

[Hoverbear]

I'm marking this as complete as the specific case described is resolved (the prompt is more natural around uninstalling.), a test on the current main with a --nix-package-url flag which is nonsense results in a working uninstall, so the underlying issue, if one existed, also was resolved.
