GPG key issues causing package update failures

Inizia dall’output dell’aggiornamento dei pacchetti non riuscito per planet.nyc1.psf.io e verifica il Python issue #568 indicato, in relazione ai vincoli di Ubuntu 18.04 e Python 2. Traccia dove sono configurate le chiavi dei repository di datadog, nginx e Salt; il lavoro è completato quando gli aggiornamenti dei pacchetti non falliscono più la verifica della firma senza compromettere la configurazione supportata dell’host.

May be able to fix by updating to new keys (datadog, nginx, salt) but also this host is far out of support range (18.04) but is stuck due to python2 (See: https://github.com/python/planet/issues/568#issue-2417204196)
