I always get the following errors when I do sudo apt-get update. How do I fix them?
W: Duplicate sources.list entry http://archive.canonical.com/ubuntu/ oneiric/partner i386 Packages
(/var/lib/apt/lists/archive.canonical.com_ubuntu_dists_oneiric_partner_binary-i386_Packages)
W: You may want to run `apt-get update` to correct these problems
