Greetings, Someone correct me if I am wrong, but given that Ubuntu is a Debian-based system, it should not break things if you add the debian.koha-community.org repository and try grabbing what you need from there. http://wiki.koha-community.org/wiki/Koha_3.8_on_Debian_Squeeze This gives the line you need to add into an /etc/apt/sources.list.d/koha.list file Make sure to get the key too! The command is in the "Everyone" part just below the repository options. Update the libraries available listing: $ sudo apt-get update Then try to apt-get them. Hopefully by pointing to the koha-community.org repository this will solve your problems. I don't know if this will or not, as I have yet to do a 64-bit install, but it can't hurt to try. :) 3.6.X and 3.8.X have different dependencies, and some don't exist nicely in the purely default Ubuntu world. Just my thoughts. No guarantees. Regards, Mark Tompsett
