Bug Description
$ system-image-cli -i
current build number: 171
device name: m75
channel: ubuntu-
last update: 2015-04-14 22:23:10
version version: 171
Upon boot, my v6 routes include a default via ccmni0:
$ ip -6 route
fe80::/64 dev wlan0 proto kernel metric 256
default dev ccmni0 proto static metric 1024
Even though there's no v6 address on the device:
$ ip -6 addr
1: lo: <LOOPBACK,
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
10: wlan0: <BROADCAST,
inet6 fe80::3abc:
valid_lft forever preferred_lft forever
This means that hosts that have v6 addresses are tried to be reached via v6, which obviously fails:
> 29% [Connecting to ports.ubuntu.com (2001:67c:
Toggling GSM data loses the default route:
$ ip -6 route
fe80::/64 dev wlan0 proto kernel metric 256
And the connection succeeds via v4.
Attached find a set of logs from network-
