我已经在 Ubuntu 20.04 上使用 Squid 4.13 大约一周了。
我最近遇到的（希望也是最后一个）问题是：
严重错误：未为 HTTPS_port 配置有效的签名证书
这是我的话：
https_port 0.0.0.0:3128 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/usr/local/squid/etc/rootCA.crt key=/usr/local/squid/etc/rootCA.key options=SINGLE_DH_USE,SINGLE_ECDH_USE tls-dh=/usr/local/squid/etc/dhparam.pem
我已经到处找过了（至少感觉如此），甚至 squids 自己的 wiki（https://wiki.squid-cache.org/ConfigExamples/Intercept/SslBumpExplicit) 是 vierd？因为一开始他们展示了如何制作 .pem 文件，但在文档末尾他们展示了示例行，他们谈论的是 .crt 和 .key 以及完全不同的 .pem 文件。
我唯一改变的是将位数提高到 4096
所以我又迷路了！有人知道他们在说什么吗？正确的格式是什么，怎么做……啊！帮帮忙？
编辑：这是我正在使用的“标准”配置：

/etc/squid/conf.d 中包含的配置是一个名为 debian.conf 的文件：
#
# Squid configuration settings for Debian
#
# Logs are managed by logrotate on Debian
logfile_rotate 0
# For extra security Debian packages only allow
# localhost to use the proxy on new installs
#
#http_access allow localnet
按照要求：

答案1
解决方案的一部分是 ID 10 T 问题，显然证书有缺陷，即使测试表明它没有问题，但在创建新证书后它就起作用了。
后来出现的有关循环的问题，在这里被确定：https://unix.stackexchange.com/questions/664236/squid-proxy-is-eating-up-its-own-resources-and-other-issues
