Local Apps

[Kees]

I am trying to install firefox as a local app (following this guide:
https://help.ubuntu.com/community/UbuntuLTSPKarmicLocalAppsFirefox)
However I get stuck at the first hurdle. When I am trying to update apt
in the chroot environment it seems like it has no internet access in
there. Probably something I have done wrong in my network setup (one
nic). When I do 'sudo chroot /opt/ltsp/i386 route' or 'sudo chroot
/opt/ltsp/i386 ifconfig' both commands complain about lack of network
support.

I can log in on via ltsp and run firefox there without any problems. But
I don't seem to be able to install it as a local app.

I am not even sure where I should look for this one. If anyone can help
me that would be much appreciated.
