Re: How to switch off IPv6 on RPi3?

Excellent, thanks. As to "Why disable IPv6?" apt-get seems to prefer IPv6 mirrors if they are listed. My ISP doesn't support IPv6, so I can't get to any of those mirrors, and thus apt-get upgrade fails. Disabling IPv6 appears to force apt to pick an IPv4 mirror. It'd be lovely if my ISP could add su...
