Bug Description

Hi,

since recent upgrade /usr/share/squid-deb-proxy-client/apt-avahi-discover crashes (= uncaught exception):

# /usr/share/squid-deb-proxy-client/apt-avahi-discover
Traceback (most recent call last):
  File "/usr/share/squid-deb-proxy-client/apt-avahi-discover", line 126, in <module>
    address = get_proxy_host_port_from_avahi()
  File "/usr/share/squid-deb-proxy-client/apt-avahi-discover", line 109, in get_proxy_host_port_from_avahi
    hosts.append(AptAvahiClient(addr))
  File "/usr/share/squid-deb-proxy-client/apt-avahi-discover", line 44, in __init__
    self.connect( (addr[0], addr[1], 0, 0) )
  File "/usr/lib/python2.7/asyncore.py", line 356, in connect
    raise socket.error(err, errorcode[err])
socket.error: [Errno 101] ENETUNREACH

Reason: There's a problem with the avahi daemon running on the machine with squid proxy server. It always advertises an official IPv6 address, but its firewall allows a fe80:: address only, i.e. it advertieses an IPv6 address where the Port of the proxy is not available. While this is definitely a problem and misconfiguration of the proxy server, apt-avahi-discover should not crash, but simply not report that proxy server as found.

regards

I have a similar problem with a host when n2n is running. Apparently, the proxy server (apt-cacher-ng in my case) is being advertised via avahi but probing the IP:port combination of the n2n interface shows the port as closed. This is 100% reproducible.
