that's interesting my firefox browser was blocking the elements of the mesa page that had links to downloads&info and I only found out because of your direct link heh. That's exactly what I assumed and expected should be there, but couldn't see. thank you.

stuck here 7. Add the LinuxCNC Archive Signing Key to your apt keyring by running

sudo apt-key adv --keyserver hkp://keys.gnupg.net --recv-key 3cb9fd148f374fef

failed no such file or directory output was

See if this helps (or maybe confuses things twice as much):

I had trouble getting going with this too. I haven't used linux daily for years, but some things are beginning to come back to me. Some things have improved since then too.

Ok I have this installed and edited the interfaces file without errors.
does this look right?

still having problems W2 is down W3 is up

If eth0 is the name of the interface you want to use.

The only reason I say that is unless you have made changes to the way the kernel names the network interfaces generally ethX (ie eth0) is not used.
Lists your interface names, if eth0 is listed all good, if not eth0 will not work in the above.
