I am on Ubuntu 16.04. When running sudo apt-get upgrade I obtain

The following packages will be upgraded: akregator-trinity amarok-common

Etc all together some 66 packages

Then even saying yes I obtain

Can somebody please tell me what is wrong here?

I'm on Debian not Ubuntu so I can't be certain but it looks like you forgot to run apt-get update first which would have told your system to download maybe pre16 instead of pre13.
