Sometimes feels like there's an echo in here !

When I looked this up a week or so ago, it's a "known issue" with APT that the 
message is misleading. It tries all addresses returned in order - so if the 
IPv4 addresses fail then it'll also try IPv6 even if the machine isn't 
configured with IPv6 (IMO this is wrong). When it runs out of addresses it 
spits out the above report which really means "I couldn't connect to any 
address".

So taking a step back, it suggests that apt couldn't connect to the IPv4 
addresses.
