Per default, the automated ipv6 link-local address will be the same at
every boot (It uses the MAC/HW-address to generate it).

If you can ssh to the PI card from Windows and OS-X, then the PI card is
working. Try first to ssh manually, as you tried earlier, but you need to
fill in the correct IPv6 address.

If you run
dpkg -l|grep avahi
and
dpkg -l|grep mdns
on the ubuntu machine, it will list all packages installed that contains
avahi or mdns in its name.

Looking at https://help.ubuntu.com/community/HowToZeroconf , either
avahi-daemon or mdnsresponder needs to be installed (and running) in order
for zeroconfig name resolving to work.
