install failing on latest Bluefin

[cpnfeeny]

On a fresh install of Bluefin, I can't get the installer to work. See the error of the self-test below.

I do notice that the path /nix/var/determinate/ doesn't exist.

Yeah, this is a bug that I keep forgetting to fix. I'll send out a PR shortly, but you can essentially ignore that, assuming you can access Nix inside your shells (a simple nix store info will validate).

[cpnfeeny]

Hmmm.

But if I try to add a channel and then update, I get

$ nix-channel --update

unpacking 1 channels...

Or perhaps this problem is unrelated to the bug you mentioned?

Thanks!

[cpnfeeny]

Or it's the same 'just ignore it' bug?

[cole-h]

Could you try restarting your nix-daemon? sudo systemctl restart nix-daemon should do it.

If it fails to start up, I'd be interested to know why.

(The post-build-hook is something that should be created by determinate-nixd, so the fact it's not there at this point is a little suspicious. It not being there during the self-test is "maybe ok", but it not being there after that is weird.)

I also noticed this error when installing Nix using this installer on my Fedora Silverblue PC, so as a workaround I just created the parent directory and touched the script in question. It seems like it worked afterwards and I'm not aware if there are any other problems so far.

[Hermitter]

On Silverblue, I ran into the same issue. It seems the installer doesn't correctly set up nix when installing with --determinate.

I haven't been keeping up with all the changes and didn't realize that the prompt Cut the fuss with Determinate Nix? wasn't just confirming with me to run the Determinate Nix Installer as before.

After uninstalling and then telling the installer no for Determinate. Everything is working now.

bash-5.2$ curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | \
  sh -s -- install

Cut the fuss with Determinate Nix? 

Proceed? ([Y]es/[n]o/[e]xplain): n
