如何發出 apt-get 更新？

運行命令後sudo apt-get update

我收到以下錯誤：

W: GPG error: https://deb.nodesource.com/node_7.x xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1655A0AB68576280
W: The repository 'https://deb.nodesource.com/node_7.x xenial InRelease' is not signed.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.

我怎樣才能解決這個問題？

答案1

您使用的儲存庫存在安全憑證問題。在儲存庫維護人員修復此問題之前，完成更新的唯一方法是停用該儲存庫。如果只有兩者，那應該不是什麼大問題，而且問題應該是暫時的——每次回購未通過安全檢查時，都應該通知回購維護者。

答案2

您可以從'curl -s 取得金鑰http://nsolid-deb.nodesource.com/gpgkey/NODESOURCE-NSOLID-GPG-SIGNING-KEY'

要修復該錯誤，您必須匯入您正在使用的儲存庫的金鑰。若要匯入儲存庫的金鑰，請執行下列命令

curl -s http://nsolid-deb.nodesource.com/gpgkey/NODESOURCE-NSOLID-GPG-SIGNING-KEY | sudo apt-key add -
