Thanks Simon. Yes, the nginx package probably failed to upgrade because the service didn't start. And it didn't start because of a missing certificate:
-- Boot 0baea423fe7d453f9d1f6091bc398839 -- Starting A high performance web server and a reverse proxy server... nginx: [emerg] cannot load certificate "/etc/ssl/certs/heliosd.crt": BIO_new_file() failed (SSL: error:80000002:system library::No such file or directory:calling fopen(/etc/ssl/certs/heliosd.crt, r) error:10000080:BIO rou> nginx: configuration file /etc/nginx/nginx.conf test failed nginx.service: Control process exited, code=exited, status=1/FAILURE nginx.service: Failed with result 'exit-code'. Failed to start A high performance web server and a reverse proxy server. But as I mentioned previously, that should not have crashed the installer. And to be clear, by installer I'm not talking about the nginx package maintainer scripts, but during upgrade from Impish to Jammy via do-release-upgrade(8). Sorry if that wasn't clear before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1977667 Title: package nginx-core 1.18.0-6ubuntu14.1 failed to install/upgrade: installed nginx-core package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nginx/+bug/1977667/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
