Upgrading ngnix on 16.04 from 1.10.1 to 1.10.2 reports the following at the end of the upgrade:

Seems to be the same problem on Trusty as well.

Same on trusty, I had to temporarly patch the failing postinst scripts in /var/lib/dpkg/info/ to just return to get it installed.

[Thomas Ward (teward)]

Davide: Mind including a diff identifying what you changed?

[Davide (darkenergyreactor)]

I inserted a 'return' at the beginning of the following postinst scripts, but I didn't have time to check why they fail:
/var/lib/dpkg/info/libnginx-mod-http-image-filter.postinst
/var/lib/dpkg/info/libnginx-mod-http-subs-filter.postinst
/var/lib/dpkg/info/libnginx-mod-http-upstream-fair.postinst
/var/lib/dpkg/info/libnginx-mod-http-xslt-filter.postinst
/var/lib/dpkg/info/libnginx-mod-mail.postinst
/var/lib/dpkg/info/libnginx-mod-stream.postinst

This is just a quick workaround to fix the broken dependencies.

Near the end of the installation process you'll also see invoke-rc.d failing because 'upgrade' is not supported (maybe service should be used instead?)
