我有一台 Ubuntu 机器（20.04.3），其中 nginx 已经因段错误而停止两次：

两次都发生在 logrotate 之后不久。我有一个崩溃转储，如果需要的话可以上传。顺便问一下：有没有一个好的网页可以解释如何读取崩溃转储？我试图将其作为错误提交到 launchpad，但收到以下消息：

*** Problem in nginx-extras
The problem cannot be reported:
You have some obsolete package versions installed. Please upgrade the following packages and check if the problem still occurs:
libssl1.1, openssl
Press any key to continue...
但是 libssl1.1 和 openssl 是最新的!?!？
谢谢。Bernd
