How do I install root certificate?

As I understand it, the root certificate is only installed on the client.

To use the public key for signing packages, the root certificate needs to be installed on the server. How do I install the root certificate on the server? Is there an easy way?

After the initial install of Ubuntu 14.04, open the package manager and search for openssh-server. Install the openssh-server and then you can create a keypair for that server.

The next step is to add the certificate that you have created in .ssh/idrsa.pub (or in /home/user/.pub).

Ssh-copy-id -i ~/.pub user@server Now you should be able to login with your private key as root. If the certificate expires, you will have to restart the server to renew the certificate.
