Nginx-relevant information from DpkgTerminalLog has been extracted and translated through Google Translate so I can read it. That's attached here.

We are missing information still for debugging this. There also appears to be a different issue as well with apport hooks.

I need you to include the output of the following command, please, as either a comment on your bug or as an attachment:

systemctl -l nginx.service status

This will likely contain additional information, because it failed to start after configuring the package, which suggests something else is at play, and the error message was not obtained here.

[Thomas Ward (teward)]

Also, please refresh your apt information with `apt-get update`; there was a recent upload of nginx 1.9.10-1ubuntu1 which addresses security issues as well as other fixes, and it is necessary to test that version rather than the older 1.9.9-1ubuntu1 which you are attempting to install.

I did not install nginx because I do not need it, now. Then with systemctl -l nginx.service status the result is ''Unknown operation nginx.service.'' but,yesterday, after apt-get update e apt-get upgrate the result was bug

[Lorenzo Tandoi (lorenzo-tandoi)]

I can solve installation nginx first, then apt-get...
but I think there is another problem and Would indeed contribute

[Thomas Ward (teward)]

There is nothing in your bug here that indicates any type of bug in the
NGINX package.

Without further debugging information, there is nothing here to suggest
any type of bug in the NGINX package, or in others. Therefore, without
any additional debugging information, and since you said you no longer
need it, I am going to leave this bug as Incomplete until such time
there's sufficient debugging information to determine whether this is or
is not a bug.

[Thomas Ward (teward)]

Digging around further in your Dpkg History that was attached here, it looks like you have Apache installed. Nginx won't start if port 80 is bound to, but without the additional bug information I can't determine if that's the issue (though it's likely one of the main culprits)

[Lorenzo Tandoi (lorenzo-tandoi)]

I confirm the previous installation of Apache. I installed radically nginx, apt-get ... and problem solved
