Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 imagej : Depends: openjdk-6-jre but it is not going to be installed or
                   sun-java6-jre but it is not installable
W: Duplicate sources.list entry precise/partner i386 Packages (/var/lib/apt/lists/archive.canonical.com_ubuntu_dists_precise_partner_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems
E: Unable to correct problems, you have held broken packages.

How I can fix this ? Update doesn't work, server change too. And it's with all SW, which I try to install... Feel really lost.

Firs you should check the duplicate line the system is warning you about:

gksu gedit /etc/apt/sources.list

Search for the line duplicated and remove it, or disable it by adding # at the begining of the line.

Then, update the system:

sudo apt-get update
sudo apt-get upgrade

And try again to install the software:

sudo apt-get install imagej

Note that the last "j" is NON capital.
