It is. Point releases like 12.04.1 and 12.04.2 are not considered
different releases from the original release (in this case, 12.04).
Depending on the machine's configuration, do-release-upgrade is looking
for either the next LTS or the next interim release (eg, 14.04 LTS or
12.10), neither of which are released yet. A point release is
essentially a recollection of all the updated packages for that release
on an updated ISO. These updated ISOs help reduce the number of package
updates after OS install (or during OS install, if you choose to install
updates during install).
To upgrade to the point release, just use your site's regular procedures
for keeping machines up to date. If the machines are configured with
precise-updates enabled (the default) and you have been applying updates
all along, then there nothing more for you to do. This can be confirmed
by observing the output of:
$ lsb_release -d
Description: Ubuntu 12.04.1 LTS
