请参阅屏幕截图以了解颜色： apt-get 更新错误屏幕截图
这是我的/etc/apt/sources.list内容：
deb http://ftp.fr.debian.org/debian/ stable main contrib
我还尝试从这篇文章启动此命令https://askubuntu.com/questions/277793/getting-server-certificate-verification-failed-during-apt-get-update/277796#277796:
apt-get update -o Acquire::https::mirror.ufs.ac.za::Verify-Peer=false
但我得到同样的错误。
答案1
这里有关于需要做什么的解释： https://dev.mysql.com/doc/mysql-apt-repo-quick-guide/en/#repo-qg-apt-repo-manual-setup
基本上你需要运行这个命令：
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8C718D3B5072E1F5
对于 Debian 9，您的系统中应该有以下内容/etc/apt/sources.list文件：
deb http://ftp.fr.debian.org/debian/ stretch main
deb-src http://ftp.fr.debian.org/debian/ stretch main
deb http://security.debian.org/debian-security stretch/updates main
deb-src http://security.debian.org/debian-security stretch/updates main
答案2
我将屏幕截图作为答案发布，以便您可以看到。
