Cannot upgrade to Ubuntu 16.04

For months I’ve been putting off upgrading to Ubuntu 16.04, but now I think is a good time to do so, however I can never manage to get past the following message:

After updating your package information, the essential package ‘ubuntu-minimal’ could not be located. This may be because you have no official mirrors listed in your software sources, or because of excessive load on the mirror you are using. See /etc/apt/sources.list for the current list of configured software sources. In the case of an overloaded mirror, you may want to try the upgrade again later.

I have checked in /etc/apt/sources.list and see no reference to ubuntu-minimal. Any ideas?

What I would do is first, login to the DigitalOcean Control Panel and take a snapshot of your current Droplet, this ensures you can revert back to current state should the updates & upgrades mess up your current setup/configuration.

Once the snapshot is fully complete, you may need to run:

sudo dpkg --remove ubuntu-minimal

To remove the conflicting package and then run the upgrade process again.
