如何发出 apt-get update？

运行命令后sudo apt-get update

我收到以下错误：

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

我怎样才能解决这个问题？

答案1

您使用的存储库存在安全证书问题。在存储库维护人员修复该问题之前，您能够完成更新的唯一方法是禁用该存储库。如果只有这两个问题，那应该不是什么大问题，而且问题应该是暂时的——每次存储库未通过安全检查时，都应该通知存储库维护人员。

答案2

您可以通过“curl -s”获取密钥http://nsolid-deb.nodesource.com/gpgkey/NODESOURCE-NSOLID-GPG-SIGNING-KEY‘

要修复该错误，您必须为正在使用的存储库导入该密钥。要为您的存储库导入密钥，请运行以下命令

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