It's quite rare that IPv6 screws with anything these days. People tend
to either have it and it just works, or they don't have it. Because
almost everything tries IPv6 first, it's common to see lots of IPv6
"error messages" on systems with no IPv6 connectivity.
Otherwise I'm with Colin - settings rather than a defect.
This is a wild shot in the dark, but those "trust chain broken"
messages could be evidence of a clock issue (the crypto protecting most
major domains these days relies on agreed time). Make sure your
computer time is set correctly. If you have a local resolver on your
network, make sure its time is set correctly too. Though it would be a
bit odd for the time to differ between the live CD and the real system.
Looking at that log, this feels like a DNS or routing issue, not a
hardware issue (except for the time, maybe). On a different computer,
look up www.google.com and try pinging its IPv4 address (or any of its
IPv4 addresses) from the problem child. If the ping gets there, you
have a DNS problem. If the ping doesn't get there, we can look
further...
Regards, K.
