The update fails at the first boot of the board

[dido18]

Motivation

When the board is booted the first time, the update always fails. After the first restart, the update works as expected.

Error in the AppLab:

Error in the Console log:

Error: {"details":"Error checking for upgradable packages: no internet connectivity"}

Root cause

Before doing a system update, Arduino App CLI checks the internet connectivity by performing a HEAD https://download.arduino.cc

The check fails with the error:

"Head \"https://downloads.arduino.cc/[\](https://downloads.arduino.cc//)": tls: failed to verify certificate: x509: certificate has expired or is not yet valid: current time 2025-09-09T09:03:56Z is before 2025-10-28T08:59:20Z

This TLS verification fails because the board does not have the internal clock updated. This causes the TLS verification to fail.

Possible solution

A possible solution is to force the board to update the datetime (when? at first startup? every time an update check?).
