To better understand, I have created a virtual machine with Ubuntu
12.04 and tried myself. In fact:

pgis at pgis-ubuntu64-vm:~$ sudo apt-get install grass70 grass70-gui

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:
 grass70 : Depends: grass70-core but it is not going to be installed
 grass70-gui : Depends: grass70-core but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
pgis at pgis-ubuntu64-vm:~$


So I tried harder:

pgis at pgis-ubuntu64-vm:~$ sudo apt-get install grass70 grass70-core grass70-gui
Reading package lists... Done
Building dependency tree
Reading state information... Done

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 grass70-core : Depends: libgdal1h (>= 1.8.0) but it is not installable
                Depends: libgeos-c1 (>= 3.4.2) but it is not going to
be installed
                Depends: libproj0 (>= 4.8.0-1) but it is not going to
be installed
                Recommends: gdal-bin but it is not going to be installed
                Recommends: proj-bin but it is not going to be installed
                Breaks: grass70 (< 7.0.0+0ubuntu3~)
E: Unable to correct problems, you have held broken packages.

Not sure what the next step is (I am more experienced with RPM based systems).

Likely it can be solved :-)
