Hi,

Can you try

sudo dpkg -i --force-overwrite /etc/logrotate.d/nginx

which will attempt to overwrite the specific file that failed.
You could also do --force-all instead

I got this error now:

dpkg-deb: error: `/etc/logrotate.d/nginx' is not a debian format archive
dpkg: error processing archive /etc/logrotate.d/nginx (--install):
 subprocess dpkg-deb --control returned error exit status 2
Errors were encountered while processing:
 /etc/logrotate.d/nginx

Ah, ok, sorry. Let's try
sudo dpkg -i --force-overwrite /var/cache/apt/archives/nginx_1.8.0-1~trusty_amd64.deb

You may also want to try uninstalling with --purge first, as the third party repo with the newer Nginx build may not have the common package split out.

It worked but now PHP won't be read... Hmmm

I am only getting a white screen now... I can not figure out what the problem is at the moment... I think that the latest nginx does not work with the latest php5-fpm? Do you have any idea on what is going on here?

I'm not sure. On my end I am still using the version that ships with Ubuntu 14.04. Are you seeing anything in the logs for either Nginx or PHP?

Hi,
I faced similar error as damlr and I followed everything BrookDo mentioned. I am getting a white screen now. Can you tell me where to look now or how to debug the problem?

Hi I solved the problem almost instantly after my report regarding the blank page!

The problem is in the config files. Make sure that the correct site is active and not the deafult NGINX welcome site! Check the paths!

sudo apt-get remove nginx-common
sudo apt-get install nginx

This works for me.

The issue of the whitescreen problem is that fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; needs to be added to the fastcgi_params file.
