Verbose mode

When for whatever reason an error keeps occurring and needs some back and forth, it's a bit inconvenient to run the curl command, copy the log location, and tail it repeatedly. It would be nice if we had an environment variable to make the script print everything it writes in logs, directly to stdout.

Also when it is retrying to fetch a url, it may take a few minutes until the process finishes and prints the location of the log file, while if it printed the errors in stdout simultaneously (when the environment variable is set) one could immediately see it is a network error and act, saving time.

La issue non indica file, test o punti di ingresso. Inizia individuando il codice di logging e dei tentativi di nuovo accesso agli URL dell’installer, quindi traccia il percorso dell’output del log fino al file e quando viene stampata la posizione del log. Il lavoro è completato quando una modalità dettagliata controllata da una variabile d’ambiente rispecchia gli errori del log su stdout durante i retry senza modificare l’output normale.
