edh [1] filed a request to merge letsencrypt-git [2] into certbot-git [3]: The project has been renamed. Invoking the github page [1] already redirect to the new name. Though the new name was not yet officially announced, despite being teased, it already makes sense to rename this package since it fetches from github and is effected right now.
