在ubuntu20.04中运行sudo apt-get update报错The following signatures couldn‘t be verified because the public key

报错的具体信息：

The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E88979FB9B30ACF2

解决办法：

1、把报错信息里面的 NO_PUBKEY后面的具体KEY值复制下来，我的就是E88979FB9B30ACF2

sudo gpg --keyserver keyserver.ubuntu.com --recv-keys E88979FB9B30ACF2

运行截图如下：

此时如果运行apt-get update,仍然会报错

因此，需要继续进行下一步处理

2、运行命令，中间的KEY还是上面NO_PUBKEY后面的

找到对应的key之后直接下载，下载文件为armored-keys.asc，传到linux服务器，然后使用命令。，在里面搜索自己要找的pubkey，比如我这里搜索40976EAF437D05B5。因为一些代码库需要使用老版本gcc，我在安装gcc的时候出现问题。

通常可以使用`apt-key add`命令，但注意到从Ubuntu 20.04开始，apt-key已被弃用，推荐将密钥添加到`/etc/apt/trusted.gpg.d/`目录中。但用户可能仍需要临时使用旧方法，或者使用更安全的密钥管理方式。另外，检查...

引用4提到删除docker.list和docker.list.save文件，然后运行sudo apt update。但用户可能更希望保留仓库配置，而不是删除文件。引用5展示了使用apt-key add命令来添加公钥，但可能步骤不够详细。我需要综合这些信息...

原因是缺少这个源的两个公钥，导致无法访问，只要把公钥加到我们系统中就行。Ubuntu在source.list中添加源后，提示。

这个意思是在尝试从 https://packaging.gitlab.io/janus/focal 镜像源获取更新时，遇到了无法验证签名的问题，因为缺少相应的公钥。要解决这个问题，你需要手动添加缺少的公钥到你的系统中。根据错误信息，缺少的公钥分别是 797DFE3F4F80269B 和 D11878B3CE2B8566。我们需要从适当的地方获取这些公钥。容器里面一般会有安装一些软件调试的需求，换个源之后会出现导入gpg的错误。
