Ubuntu 20 fails as it does not have a libvirt-bin package

[cmccrorie]

Whereas Ubuntu 18 did have a libvirt-bin package, Ubuntu 20 does not. When running the following on Ubuntu 20:

class { '::libvirt':
  virtinst           => true,
  defaultnetwork     => true
}

We get errors like:

Error: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install libvirt-bin' returned 100: Reading package lists...

This may mean that the package is missing, has been obsoleted, or
is only available from another source

Is there a fix or workaround that we can use for Ubuntu 20 please?

Thanks.

The packages that need to be installed are qemu-kvm libvirt-daemon-system.
