Comment 9 for bug 1957320

You got an error in nginx-core postinst script. See

dpkg: error processing package nginx-core (--configure):
 installed nginx-core package post-installation script subprocess returned error exit status 1.

You should investigate what is going on there and ensure this is not a regression caused by the proposed changes. For example, is it a configuration issue with the sample config files that is preventing a service restart? Is it something else?

I don't believe that suggesting package re-installation would be an acceptable SRU outcome.
