There's nothing here to determine why nginx failed to install - it *does* show as running. Nothing in the output suggested by the dpkg error, either, helps to debug this as well.
Best I can suggest is to try and install nginx separately, and then try and install your application. However, your history log shows that nginx *did* get run and tried to install, and nothing in the terminal log provides usable debug information here. I'm marking this as Incomplete, until more useful debugging information can be made available. ** Changed in: nginx (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576329 Title: package nginx-core 1.10.0-0ubuntu0.16.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nginx/+bug/1576329/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
