Recupero file cancellato nel cestino con Ubuntu

[Bill Carson]

Buonasera, spero sia la sezione giusta.
Stamattina su un computer condiviso mi è stato cancellato per errore un file nel cestino (di grosse dimensioni, circa tra i 200 e i 500 giga, non ricordo). In questi casi prima si interviene e meglio è.
Ho dato un'occhiata e mi pare di capire che recuva sia il più affidabile...Da terminale faccio il comando sudo apt-get install recuva e mi chiede la password che non ho dato che avevo salvato in quel file (cancellato) la password, come faccio? Su Ubuntu Software non me lo trova, esiste un software simile?

Edit: Questo è il massimo che sono riuscito a fare:
