The four that "apt list --upgradable" lists. You have two updates wich are 
held back ("not upgraded"). Probably you've set them to "hold" with "apt-mark".

You should set them back to normal with "sudo apt-mark unhold" - unless you 
really need the older versions. Then you can do "sudo apt full-upgrade". 
Notice the "full-". 

After that you can do "do-release-upgrade" or "update-manager -c" if you 
like. (I don't know it.)


Bye,
