Sorry, try the path
/scratchbox/users/YOUR_USERNAME/targets/FREMANTLE_ARMEL/etc/resolv.conf
but don't just copy it into the terminal it's not a command we just want to see if the file exists then inspect it's contents if it does.

(your exact location may be slightly different)

you should be able to browse for it through your file explorer from the host environmente.

If it genuinely doesn't exist you can copy your host's version to that location.
