Trying to install sage 5.3 server on a dell poweredge 1650 running Lubuntu 12.04. I have been battling with this install for quite some time, our previous sage server ran on a poweredge 1750 in a Virtualbox VM, using Ubuntu 10.04 with a gnome GUI (very minimal). We had other VMs running on that server that have been relocated, so the consensus was to simply build a new sage server using a minimal LXDE desktop on the 1750. This was the first hurdle, 12.04 doesn't seem to like to load the network drivers from the mini install CD, no DVD drive. This prompted me to use a 1650 that the operating system loads fine on. However the new sage 5.3 spits out errors like this " This sage install was built on a machine that supports instructions that are not available on this computer. Sage will likely fail." I have a two pronged attack going on right now, one is trying to make our old virtual machine run on 12.04 just to get the math department a sage server. The second approach was to try and compile sage on my other 1650, and see if that would fly. Neither of these approaches have done me much good, and I am running out of hair to pull out. Anyone out there has any tips and tricks they would like to share on this matter?
