newbie apt-get question

[Mark D. Hansen]

I'd like to upgrade to version 3.0.5 of SAMBA.  But, apt-get tells me that "samba is 
already the newest version".  When I try this:

apt-get install samba=3.0.5

it tells me that "Version 3.0.5 for samba is not found"


What am I doing wrong?

Thanks,

Mark
