W: Duplicate sources.list entry stable/main amd64 Packages (/var/lib/apt/lists/
W: Duplicate sources.list entry stable/main i386 Packages (/var/lib/apt/lists/
W: You may want to run apt-get update to correct these problems

I get this every time I do something with apt-get. How do I get rid of this error message?


This is what my sources.list looks like:

missingfaktor@going-merry /etc/apt/sources.list.d $ cat /etc/apt/sources.list
# /etc/apt/sources.list

# deb lucid main
# deb-src lucid main
# deb maya cairo-dock ## Cairo-Dock-Stable

@JorgeCastro, please see the update. – missingfaktor Sep 11 '12 at 22:02

Have a look at the other files in /etc/apt/sources.list.d/ . Files in those folders are also used by apt-get, and it's quite likely that you have two files in that folder referencing the same PPA (or one file in there referencing it twice).
