It seems that octave is not installed in your virtual machine. Did you
install it? If it is so, try in a console
octave --version

Could you click on the left where the error message appear and
copy/paste here the full traceback of the error.

I managed to install both pieces of software, although oddly now Sage
notebook is having trouble starting octave & doesn't recognize that
PDFLatex has been installed. I ran these commands through the
terminal:
sudo "yum install octave texlive"
as Sage 6.6 seems to run through Cent OS even though I set the OS for
the
virtual machine (VM) to Ubuntu (32 bit). I then closed the VM and
re-opened
& re-ran these commands. Attached is a screenshot showing my exact
errors
in sage notebook relating to PDFLatex & Octave.

Hi,
I am new to VirtualBox but I have Sage running running now through it
but
I haven't a clue how to get octave & pdflatex installed on this
virtual
machine. The OS of the virtual machine on which Sage is running is
Ubuntu
32 bit. My PC is Windows 7 64 bit. I have Octave installed on my host
OS
(i.e., the Win 7 64 bit) and it is in my PATH environment variable.
Thanks for your time,
Brenton
