Action encrypt_apfs_volume errored

[rstauch]

Hi,

I am trying to run the installer (after having succesfully run it some time ago to install nix in the first place) but the following error occurs:

Error

Error: 
   0: Planner error
   1: Error executing action
   2: Action `encrypt_apfs_volume` errored
   3: The keychain lacks a password for the already existing "Nix Store" volume on disk `disk3`, consider removing the volume with `diskutil apfs deleteVolume "Nix Store"` (if you receive error -69888, you may need to run `launchctl bootout system/org.nixos.darwin-store` and `launchctl bootout system/org.nixos.nix-daemon` first)

Metadata

key	value
version	0.10.0
os	macos
arch	aarch64

Is the installer not intended to be able to upgrade an existing installation ?

Generally to upgrade Nix you should use nix upgrade-nix or uninstall (/nix/nix-installer uninstall) and reinstall.
