[Bug 1422162] [NEW] /usr/share/squid-deb-proxy-client/apt-avahi-discover crashing

[Hadmut Danisch]

Public bug reported:

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
