Comment 12 for bug 1272638

I can confirm your advice #10

Adding
192.30.252.147 codeload.github.com
to /etc/hosts results in the libraries being loaded, good !
(the gui is still unresponsive for some time, but that is another issue)

My internet setup is quite common, the usual router DSL that is "proxy" for everything, including DNS
I suspect that this issue will crop up a few more times since this is what most people have

thanks for your advice #11

I normally use the kicad-install.sh and I surely missed the further info on library handling

Thanks
