I have downloaded appropriate build-essential and linux headers files (and all dependencies....I think) from the internet and placed them on my desktop.
I am now trying to install the Atheros AR8161 driver from this package: compat-wireless-2012-11-13-pc Here is the output:
You can see from the code...or it appears to me...that build-essential and linux-headers have been installed properly.
But I am still getting these error messages. Why?
