The device in question indeed does not have a 'scope global' address:
https://en.wikipedia.org/wiki/Unique_local_address

says that fd00::/8 is a 'unique local address'.
I'm not sure why charmhelpers isn't happy to use them.

Note, though that the description there says you probably shouldn't use
fd00::/8 directly, but should use a randomly-generated prefix.

Generally it seems like it is a charmhelpers issue, rather than a Juju
issue.

Generally it seems like it is a charmhelpers issue, rather than a Juju
