[Bug 1448500] [NEW] tftp-hpa doesn't accept IPv4 connections

[Nick B.]

Public bug reported:

After upgrading to 15.04 on my server it seems tftp-hpa is not listening
and/or accepting IPv4 connections. When an IPv4 client tries to connect
this shows up in syslog

in.tftpd[4295]: connect: Address family not supported by protocol

netstat shows it's only listening on IPv6
sudo netstat -lp | grep tftp                                                                
udp6       0      0 [::]:tftp               [::]:*                              14327/in.tftpd

If I change the TFTP_ADDRESS option in /etc/default/tftp-hpa from
"[::]:69" to "0.0.0.0:69" it works. But this breaks IPv6
