MySQL：签名验证期间发生错误[重复]

  • 772

通过 VirtualBox，即使在不同的机器上，我也有 2 个运行以下信息的 Ubuntu Server 20.04 实例：

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.3 LTS
Release:        20.04
Codename:       focal

两者都安装了 MySQL，其指令与我几个月前使用的指令相同。sudo apt update当我确实出现以下内容时，突然间仅针对其中一个：

    您将需要为存储库导入缺少的 GPG 密钥，如下所示：

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 467B942D3A79BD29

    然后更新：

    sudo apt update

    你应该很好??
