I started experiencing the exact same problem after the most recent update of the Android SDK on my Ubuntu 16.04. In that case, you may want to try to reverse the steps above if IPv6 is already enabled on your system and the emulator does not start. Update Jan 5, '18: At least one user reports that disabling a previously enabled IPv6 has resolved the problem on his system. If you see 1 above, edit your /etc/nf file and comment out all the IPv6 disable directives: # .disable_ipv6 = 1
$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6 I found an interim workaround - make sure IPv6 is enabled.
