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?sage-introSat, 10 Nov 2012 12:08:01 -0600http://ask.sagemath.org/question/9518/How do I Open the Web-Browser-based interface when I receive the error in the Description?http://ask.sagemath.org/question/9524/how-do-i-open-the-web-browser-based-interface-when-i-receive-the-error-in-the-description/I am running Ubuntu 12.10 i386 on Vostro 3500 dell laptop.

Any help of how to resolve this error will be greatly appreciatedBrenton HorneSat, 10 Nov 2012 23:16:18 -0600http://ask.sagemath.org/question/9524/Installing a sage 5.3 cell serverhttp://ask.sagemath.org/question/9447/installing-a-sage-53-cell-server/I just did a fresh install of SAGE 5.3 on a clean Ubuntu 12.04 LTS, with essentially no problems at all. Now I would like to use it as a cell server too. Can anyone point me to a page with up-to-date instructions on how to do this?
Just to be clear: I want to use the same SAGE installation as both a notebook server AND a cell server.Dirk DanckaertFri, 19 Oct 2012 11:05:34 -0500http://ask.sagemath.org/question/9447/Uploaded images not publishedhttp://ask.sagemath.org/question/9453/uploaded-images-not-published/I uploaded an external image to a SAGE 5.3 notebook, running on Ubuntu 12.04, inserted the image in a text area, then published the notebook. It turns out a visitor who views the published notebook doesn't see that external image, although the html-code served by SAGE contains a link like 'data/image.jpg'. When logged in, users do get to see the image.
What's going wrong? Has it something to do with access rights on the server? And what should I do to correct this behaviour?Dirk DanckaertSun, 21 Oct 2012 10:43:21 -0500http://ask.sagemath.org/question/9453/
