sure
you have some choices.
1 ) install from source ( preferrerd by the developers )
http://www.jadota.com/2013/01/installing-samba4-on-ubuntu-12-04/
2 ) use the sernet packages for ubuntu : if you want an easy install with
apt-get
https://lists.samba.org/archive/samba/2013-October/176380.html
This one is about a domain join, but follow the wiki and look at the webpages.
It wil provide the info you need.
in both cases you wil have a working setup, from that point jou can upgrade your
old samba 3.x
For the upgrade, look at the wiki. ;-)
