[Bug 1758004] Re: [Ubuntu 18.04] Error installing the "Basic Ubuntu Server"

[Steve Langasek]

I have deployed a local workaround on the image build server to have
germinate consider versioned provides, so a new daily image is now
available that has the correct set of packages included in the package
pool.

This could negatively impact other image flavors, in which case we might
have to revert it again until proper germinate support for versioned
provides can land.  However, the risk to live images is comparatively
small as there's very little of import in the package pools anyway.
