By default, some operating systems do not trust the GPG key for the SUSE Manager client tools. The clients can be successfully bootstrapped without the GPG key being trusted. However, you will not be able to install new client tool packages or update them until the keys are trusted.

过程：在客户端上信任 GPG 密钥

  1. On the SUSE Manager Server, at the command prompt, check the contents of the /srv/www/htdocs/pub/ directory. This directory contains all available public keys. Take a note of the key that applies to the client you are registering.

  2. 打开相关的引导脚本，找到 ORG_GPG_KEY= 参数并添加所需的密钥。例如：

    uyuni-gpg-pubkey-0d20833e.key
      You do not need to delete any previously stored keys.
. If you are bootstrapping clients from the {productname} {webui}, you will need to use a Salt state to trust the key.
  Create the Salt state and assign it to the organization.
  You can then use an activation key and configuration channels to deploy the key to the clients.
