[Koha-devel] Koha sources

[Paul A]

I've just noticed that our Ubuntu 12.04 LTS servers are giving warnings on 
apt-get update:

W: Duplicate sources.list entry http://debian.koha-community.org/koha/ 
squeeze/main amd64 Packages 
(/var/lib/apt/lists/debian.koha-community.org_koha_dists_squeeze_main_binary-amd64_Packages)
W: Duplicate sources.list entry http://debian.koha-community.org/koha/ 
squeeze/main i386 Packages 
(/var/lib/apt/lists/debian.koha-community.org_koha_dists_squeeze_main_binary-i386_Packages)

Are there any Koha dependencies required that do *not* exist in amd64 
format? I'm only cautious as I seem to remember having to clean out i386 
packages (perhaps not even Koha) at some previous point.

Thanks and best for 2014 all around.

P.S. I'm still struggling to find time to absorb the intricacies of git 
with a view to assisting with "long-term 3.8.x".
