下载、导入并信任 AMD 公钥

下载 AMD 公钥。
1. 访问 AMD 下载网站。
2. 在“Download Verification”（下载验证）中，单击您已选定要下载的安装程序的对应Public Key（公钥）。请注意，每个安装程序文件都有一个独立的公钥。
  
  这将下载 xilinx-master-signing-key.asc。
3. 确认 AMD 公钥下载并导入成功。

要导入公钥，请输入以下命令：

gpg --import
						./xilinx-master-signing-key.asc

gpg --import ./xilinx-master-signing-key.asc
gpg: keybox '/home/myuser/.gnupg/pubring.kbx' created
gpg: /home/myuser/.gnupg/trustdb.gpg: trustdb created
gpg: key 0x85D4B4BB1D692FDB: public key "Xilinx, Inc. (Xilinx Software signing key) <software@xilinx.com>" imported
gpg: total number processed: 1
gpg:               imported: 1
myuser@mymachine:4

请将信任级别设置为 ultimate。这将允许对 AMD 签署的公钥进行验证。

首先，输入以下命令以列出公钥：

gpg
								--list-keys

gpg --list-keys
/home/myuser/.gnupg/pubring.kbx

Please decide how far you trust this user to correctly verify other users' keys
(by looking at passports, checking fingerprints from different sources, etc.)

  1 = I don't know or won't say
  2 = I do NOT trust
  3 = I trust marginally
  4 = I trust fully
  5 = I trust ultimately
  m = back to the main menu

出现提示时，请输入 5。

Your decision? 5
Do you really want to set this key to ultimate trust? (y/n) y
