Oh no, something went wrong. If you can take all the output and open
an issue, we'd love to fix the problem so nobody else has this issue.

We'd love to help if you need it.

Looks like the installation script did a lot of changes before it failed. At the beginning of the script, there was a promise, that every change can be undone quite easily. What do I have to do now, to revert the changes done?

Update: I've remove that user (_nixbld1 [it was the only one created]) und rerun the installation script, with the very same result. Looks like the script is creating the user and then somehow stumbles over it (maybe tries to create it a second time?).

Same issue as #6153.

You'll have to follow the uninstall instructions to clean up first: https://nixos.org/manual/nix/stable/installation/installing-binary.html#macos

There's more context in the linked issue, but you'll either need to clear out whatever is holding the uid, or modify the installer to use a new one.

Yes, it seems to be exactly the same issue. I have already a user with the ID 301
