$sudo nginx -t
返回：
PassengerLoggingAgent: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by PassengerLoggingAgent)
2018/06/04 02:28:40 [alert] 10411#0: Unable to start the Phusion Passenger watchdog because it encountered the following error during startup: Unable to start the Phusion Passenger logging agent: it seems to have crashed during startup for an unknown reason, with exit code 1 (-1: Unknown error)
“`
解决方法:
如果您不依赖于已使用版本4的其他软件,则可以从bionic存储库安装所需的版本3：
sudo apt install libcurl3/bionic
这将要求您删除curl本身,libcurl4和dependend软件.在删除它们之前,请仔细考虑是否需要它们.
您仍然可以通过再次安装libcurl4和删除的软件来回滚.
