找了个 debian 13(trixie，目前版本为 13.1) 虚拟机，安装 ngcp-rtpengine mr13.5.1，很容易就成功了
本想据此编写一个 Dockerfile 是件很容易的事情
But 打脸了
第一个版本
cat Dockerfile， 内容为:
FROM debian:trixie
COPY sipwise_mr13.4.gpg /etc/apt/keyrings/
COPY <<-"EOT" /etc/apt/sources.list
deb http://mirrors.huaweicloud.com/debian/ trixie main non-free non-free-firmware contrib
deb http://mirrors.huaweicloud.com/debian-security/ trixie-security main
deb http://mirrors.huaweicloud.com/debian/ trixie-updates main non-free non-free-firmware contrib
deb http://mirrors.huaweicloud.com/debian/ trixie-backports main non-free non-free-firmware contrib
deb [signed-by=/etc/apt/keyrings/sipwise_mr13.4.gpg] https://deb.sipwise.com/spce/mr13.5.1/ trixie main
EOT
RUN apt-get update && apt-get install -y ngcp-rtpengine
结果 build 时提示下面错误信息：
10.60 W: Failed to fetch https://deb.sipwise.com/spce/mr13.5.1/dists/trixie/InRelease SSL connection failed: error:0A000086:SSL routines::certificate verify failed / Success [IP: 164.132.119.186 443]
10.60 W: Some index files failed to download. They have been ignored, or old ones used instead.
10.68 Reading package lists...
问了 deepseek, 回答是需要 update-ca-certificates
debian:trixie 镜像只有 120 M，包含的组件比较有限
访问 huawei 用 http, 没问题
访问 sipwise 用 https，但没有安装 ca，问题就在这里
于是调整成下面这个版本:
FROM debian:trixie
COPY sipwise_mr13.4.gpg /etc/apt/keyrings/
COPY <<-"EOT" /etc/apt/sources.list
deb http://mirrors.huaweicloud.com/debian/ trixie main non-free non-free-firmware contrib
deb http://mirrors.huaweicloud.com/debian-security/ trixie-security main
deb http://mirrors.huaweicloud.com/debian/ trixie-updates main non-free non-free-firmware contrib
deb http://mirrors.huaweicloud.com/debian/ trixie-backports main non-free non-free-firmware contrib
EOT
RUN apt-get update && apt-get install -y ca-certificates
RUN echo 'deb [signed-by=/etc/apt/keyrings/sipwise_mr13.4.gpg] https://deb.sipwise.com/spce/mr13.5.1/ trixie main' > /etc/apt/sources.list.d/sipwise.list
RUN apt-get update && apt-get install -y ngcp-rtpengine
再次 build ，终于成功，版本为mr13.5.1
