The issue seems to be that puppet 7.20.0-1 is a transitional dummy
package pointing to puppet-agent and puppet.service was renamed to
puppet-agent.service but cloud-init is not aware of this and tries to
enable the old puppet.service.

In puppet 7.16 puppet.service was an alias pointing to puppet-
agent.service [1].
