Full-upgrade problem

Hi guys.
I’m trying to update the system with a aptitude full-upgrade. I get a warning about dependencies and removing some packages. What’s wrong?

# aptitude full-upgrade

Accept this solution? [Y/n/q/?] 

For what you want to do aptitude full-upgrade is not recommended, apt-get dist-upgrade or apt full-upgrade is.

And apt-get upgrade if you only want to install newer packages without removing anything.

I’ve always used full-upgrade in Ubuntu and Debian hosts and no problems =)

But I think I understand where the problem is.
I tried to install the kernel 3.16, added a utopic in the sources, and have a low priority to prevent update all packages:

Package: *
Pin: release n=utopic
Pin-Priority: 390

And it is obvious that something is not working as I was and conflicts during the upgrade was because of this. I rolled the changes in sources and update went without conflicts.
But the question of installing the kernel is still important. How to properly install a new kernel (from utopic)?
