Invalid package information

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.

Your /etc/apt/sources.list file only has entries for the main component of the archive with http://mirrors.digitalocean.com/ubuntu/ which is not an official mirror of Ubuntu. Subsequently, the upgrade was unable to find the essential package ubuntu-minimal. You'll need to either choose a different mirror or only use mirrors.digitalocean.com entries in your sources.list file and then respond Yes to the question about using an unofficial mirror and rewriting sources.list.

This seems to be an issue with virtualmin's repositories. You can see them at the bottom of your sources.list.

I just spun up two 12.04 droplets. One I immediately upgraded to 14.04. There were no issues at all. The next I installed virtualmin on. When I tried to upgrade it, I hit the same problem you described. I'd suggest opening a bug/support ticket with virtualmin.

The virtualmin entries were disabled when the upgrade was attempted and the issue here is the one I described in comment number 2.

You right about the issue Brian, but the cause is that the virtualadmin install script rewrites the user's source lists. Here's the diff between a fresh precise DigitalOcean image's source.list and one where the virtualmin install script has been run:

So the probelm is that their install script tries to make sure universe is enabled, so it ends up with the mixed list. Either way, not a bug in Ubuntu.

Thanks Brain!

Andrew, ah thanks that is rather crazy.

@Kangaroo - it sounds like you should take this up with the virtualmin developers then.
