Πρόβλημα με εγκατάσταση λογισμικού [self-solved!]

Παιδιά έχω την Mandriva 2009 και προσπαθώ να εγκαταστήσω το "system-config-printer" και στην πορεία μου βγάζει το παρακάτω μήνυμα:

Installation failed, bad rpms:
ftp://ftp.ntua.gr/pub/linux/mandrake/official/2009.0/i586/media/main/re…

Try to go on anyway? (y/N)

Αν και μπήκα στην σελίδα "http://easyurpmi.zarb.org/index.php?language=el" για update όταν πήγα να κάνω update στα "Επίσημα Μέσα" μου έβγαλε το μήνυμα:

Unable to add medium, errors reported:

unable to parse media.cfg

Medium: ()

Επίσης όταν δίνω την εντολή "urpmi.update -a" στο τερματικό βγάζει τα παρακάτω:

Και δεν είναι η μόνη φορά που το κάνει.Και άλλες φορές όταν προσπαθώ να εγκαταστήσω κάτι έχω τα ίδια αποτελέσματα.
Συμβαίνει κάτι?

HELP!!!!!!!!
