Maybe you still have some old packages installed that have been held. 
You could check with 'dpkg -l "*qgis*" | grep ii' to see all packages 
that are installed and have qgis in their name.

Sometimes, when I get stuck in such a cycle, I just uninstall all qgis 
and grass related packages with:

sudo apt-get remove "*qgis*" --purge
sudo apt-get remove "*grass*" --purge

and then reinstall

sudo apt-get install qgis grass
