Installed nightly-build, now getting this when updating apt:

W: Duplicate sources.list entry http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-build-dep... precise/main amd64 Packages (/var/lib/apt/lists/ppa.quickbuild.pearsoncomputing.net_trinity_trinity-nightly-build-dependencies_ubuntu_dists_precise_main_binary-amd64_Packages) W: Duplicate sources.list entry http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-build-dep... precise/main i386 Packages (/var/lib/apt/lists/ppa.quickbuild.pearsoncomputing.net_trinity_trinity-nightly-build-dependencies_ubuntu_dists_precise_main_binary-i386_Packages) W: Duplicate sources.list entry http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-builds/ub... precise/main amd64 Packages (/var/lib/apt/lists/ppa.quickbuild.pearsoncomputing.net_trinity_trinity-nightly-builds_ubuntu_dists_precise_main_binary-amd64_Packages) W: Duplicate sources.list entry http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-builds/ub... precise/main i386 Packages (/var/lib/apt/lists/ppa.quickbuild.pearsoncomputing.net_trinity_trinity-nightly-builds_ubuntu_dists_precise_main_binary-i386_Packages)

Installation is through so I guess no biggie right now, but why?

Lines are:

deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-build-dep... precise main

deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-builds/ub... precise main

Do I need to specify the arch?
