[ubuntu-it] Duplicate sources.list entry

[Felix]

Buon pomeriggio a tutti.
Da qualche giorno ogni volta che cerco di aggiornare (#apt-get update) 
ricevo questo messaggio di errore per duplicazione sorgenti:

W: Duplicate sources.list entry http://archive.ubuntu.com/ubuntu/ 
utopic/main amd64 Packages 
(/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_utopic_main_binary-amd64_Packages)
W: Duplicate sources.list entry http://archive.ubuntu.com/ubuntu/ 
utopic/universe amd64 Packages

W: Duplicate sources.list entry http://liveusb.info/multisystem/depot/

W: Duplicate sources.list entry http://liveusb.info/multisystem/depot/ 
all/main i386 Packages 
(/var/lib/apt/lists/liveusb.info_multisystem_depot_dists_all_main_binary-i386_Packages)
W: È consigliato eseguire "apt-get update" per correggere questi problemi

Il fatto strano che sono intervenuto più volte cancellando i files 
incriminati ma la situazione non cambia.

Di seguito il mio sources.list depurato (o almeno così credo):

deb http://archive.ubuntu.com/ubuntu/ utopic main restricted
deb http://security.ubuntu.com/ubuntu/ utopic-security main restricted
deb http://archive.ubuntu.com/ubuntu/ utopic-updates main restricted
#
deb-src http://archive.ubuntu.com/ubuntu utopic restricted universe 
multiverse main
#
deb http://archive.ubuntu.com/ubuntu utopic universe
deb http://archive.ubuntu.com/ubuntu utopic-updates universe
#
deb http://archive.ubuntu.com/ubuntu utopic multiverse

#
deb http://archive.ubuntu.com/ubuntu utopic-security universe
deb http://archive.ubuntu.com/ubuntu utopic-security multiverse
#
deb http://archive.canonical.com/ubuntu utopic partner
deb-src http://archive.canonical.com/ubuntu utopic partner
#
deb http://extras.ubuntu.com/ubuntu utopic main
#
deb http://liveusb.info/multisystem/depot all main
deb-src http://liveusb.info/multisystem/depot all main
#
deb http://ppa.launchpad.net/danielrichter2007/grub-customizer/ubuntu 
utopic main
#
deb http://archive.ubuntu.com/ubuntu utopic main universe
deb http://liveusb.info/multisystem/depot all main
deb-src http://liveusb.info/multisystem/depot all main

Qualcuno mi sa spiegare in cosa sbaglio?

Grazie in anticipo a tutti.
Felice
