我正在尝试根据官方documentation安装ELK。我在使用自己的证书的公司防火墙后面。因此，在第一步中，我将使用wget的--no-check-certificate选项添加公钥。
但是，在将仓库添加到/etc/apt/sources.list.d/elastic-7.x.list之后，运行#apt-get update时出现以下错误：

我尝试将[trusted=yes]添加到.list文件中：

我想出了解决方法：通过提取由公司防火墙强加的SSL证书并将其添加到受信任证书列表中，我解决了以下问题：
echo -n | openssl s_client -showcerts -servername -connect github.com:443 2>/dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' >> $(curl-config --ca)

我通过在 uoe 中使用导致大致
/etc/ssl调试起来很不方便，希望对以后的胖子有所帮助。
