I've have Ubuntu 8.04 running in a VirtualBox under WXP. No dual boot setup necessary any more. How Cool ! Works like a charm - apart from a USB printer problem.

Installed TeX, ConTeXt and XeTeX through the Package Manager (to test whether it worked).

Now trying to update ConTeXt with

ctxtools --updatecontext

which gives

CtxTools | updating /etc/texmf:/var/lib/texmf:/usr/share/texmf:/usr/share/texmf-texlive
CtxTools | unable to change to /etc/texmf:/var/lib/texmf:/usr/share/texmf:/usr/share/texmf-texlive

whether I'm in root or not !???

What's the corresponding command for XeTeX ? ( tried --updatexetex which failed )
