[FLUG-Tech] Ubuntu 24.04: problemi con il bluetooth

[Franco Vite]

Buongiorno flugghi/e,

dopo aver inutilmente vagato per la grande rete ed aver provato le 
millanta soluzioni proposte di qua e pure di là, mi sono deciso a porre 
il mio quesito qui:

dall'ultimo aggiornamento dal portatile non mi aggancio più a nessun 
dispositivo bluetooth, cosa che invece prima facevo senza problemi.

Questo è quello che succede quando cerco di collegare la cassa:
