Απ' ότι φαίνεται έπεσες σε κάποιο συνηθισμένο πρόβλημα. Το καλό είναι ότι φαίνεται να λύνεται με κάποιες εντολές από τερματικό. Το κακό είναι ότι κι εγώ δεν ξέρω τόσα πολλά για να σε βοηθήσω. Καλύτερα να περιμένεις κάποιον από τους γνώστες εδώ γύρω να σε καθοδηγήσει για να λύσεις το πρόβλημά σου.

Ποια εκδοση του ubuntu εχεις?
