Upgrade to 16.04 fails

Question

I have an Ubuntu VM (running in VMWare Fusion) and I can no longer update my apps - software updater tells me I must update from 15.10

When I try to Upgrade the machine does nothing - I never see any upgrade happen and I seem to be stuck on 15.10

This is the window I am responding to

Answer 1

I would reccomend doing the upgrade from the console, so you can see the output.

Just do:

sudo apt-get update
sudo apt-get upgrade
sudo do-release-upgrade

And see if there are any errors in the terminal.
