Scaffolding command for new app fails due to lock file error

[jost-s]

When I execute the command to scaffold a new app under macOS, I get the following error:

$ nix run github:holochain-open-dev/templates#hc-scaffold-app-template -- web-app
do you want to allow configuration setting 'extra-substituters' to be set to 'https://holochain-open-dev.cachix.org' (y/N)? y

       error: cannot write modified lock file of flake 'github:holochain-open-dev/templates' (use '--no-write-lock-file' to ignore)

Executing the same command with the suggested option succeeds

$ nix run github:holochain-open-dev/templates#hc-scaffold-app-template --no-write-lock-file -- web-app

This should be fixed now, could you try it out again?

[jost-s]

It still shows the same error for me when running the above command.

[guillemcordoba]

Hum can you try it with refresh? Maybe it's still cached?

nix run github:holochain-open-dev/templates#hc-scaffold-app-template --refresh -- web-app

I did try it on a MacOS and it worked...

I don't know what's happening, but I get the same

$ nix run github:holochain-open-dev/templates#hc-scaffold-app-template --refresh -- web-app
error:
       … while updating the lock file of flake 'github:holochain-open-dev/templates/e443646c27ceee63e383e856aba73409c1879b74'

       error: cannot write modified lock file of flake 'github:holochain-open-dev/templates' (use '--no-write-lock-file' to ignore)

Really interesting... What's your nix version? Maybe this is a bug in nix?

[jost-s]

I have nix 2.18.2
