Bug Report

In #1480 I had a problem with the update notification string from arduino-cli containing a unicode character which doesn't map to anything by default when run under a Python [3.8] script on Windows 10, causing Python to raise an exception. The conclusion to that was that I could either sort my goldarned Python/Windows code-page out or disable the notification with:

arduino-cli config set updater.enable_notification false

While the former was in progress I did the latter but I didn't actually check that it was working because I had already updated my arduino-cli version.

My problem is that the notification remains even when I've apparently disabled it, see below. What am I doing wrong?

Current behaviour

Dumping my config, you can see that updater.enable_notification is false.

>arduino-cli config dump
board_manager:
  additional_urls: []
daemon:
  port: "50051"
directories:
  data: C:\Users\rob\AppData\Local\Arduino15
  downloads: C:\Users\rob\AppData\Local\Arduino15\staging
  user: C:\Users\rob\Documents\Arduino
library:
  enable_unsafe_install: false
logging:
  file: ""
  format: text
  level: info
metrics:
  addr: :9090
  enabled: true
output:
  no_color: false
sketch:
  always_export_binaries: false
updater:
  enable_notification: false

...but when I run, for instance, arduino-cli version the "update is available" string still pops out:

>arduino-cli version
arduino-cli alpha Version: 0.19.1 Commit: 718bbbf2 Date: 2021-09-29T08:28:11Z

A new release of Arduino CLI is available: 0.19.1 → 0.19.2
https://arduino.github.io/arduino-cli/latest/installation/#latest-packages

Expected behaviour

I would expect to see just:

>arduino-cli version
arduino-cli alpha Version: 0.19.1 Commit: 718bbbf2 Date: 2021-09-29T08:28:11Z

...no "update is available" string

Environment

• CLI version: see above
• Windows 10Pro 20H2
