When trying to clone a site with Terminus latest version 3.0.1, get the following error:
Command "site:clone" is not defined.
Terminus version 3.0.1

@aminulpantheon: Try terminus self:plugin:install pantheon-systems/terminus-site-clone-plugin. We are working on a command to upgrade Terminus 2 plugins to version 3.

Hey @uberhacker the above command doesn't work:

➜ ~ terminus self:plugin:install pantheon-systems/terminus-site-clone-plugin
[error] pantheon-systems/terminus-site-clone-plugin is not a valid Packagist project.

@dqlopez: What is your terminus --version? This command only works with Terminus 3.

@uberhacker: I had encountered the same error as @aminulpantheon using Terminus 3.0.3. I ran the command you indicated and it resolved my problem. site:clone then worked.
