Warning with "locales" on Raspberry Pi OS Lite

[leograba]

When installing the Torizon Plugin on a fresh install of 64-bit Raspberry Pi OS Lite and a Raspberry Pi 5, I saw the following warnings:

This script will:
  - Add Toradex's, Fluent Bit's and Docker's package feed to your system;
  - Install fluent-bit, docker, aktualizr and rac (remote access client) applications;
  - Create a docker-compose binary at /usr/bin;
  - Install a docker-compose systemd service;
  - Create torizon user and add it to sudo and docker groups;
  - Attempt to provision the device on Torizon Cloud using a pair code;
  - Create a log file in /tmp/install-torizon-plugin.log.
Do you want to continue? [Y/n]
Installation has started, it may take a few minutes.
Now we have to create the torizon user so remote access works out of the box. Please, fill in the password for torizon user.

Oddly enough, the config I did using the Raspberry Pi Imager did include locales:
