Nginx Nginx upgrade cosmetic fixes

Hi

I just upgrade Nginx to 1.9.11 with dynamic modules and all working great

I have a few cosmetic fixes :

---

Code:

percona-release-0.1-3.noarch.rpm [found]
        package percona-release-0.1-3.noarch is already installed
Error: problem with percona-release-0.1-3.noarch.rpm install.

Don't know if it's needed to mark this as a problem...and report it as an error...

and this:

Code:

chmod: cannot access `/var/ngx_pagespeed_cache/http,3A': No such file or directory

Don't know what is this and if it is a problem ......

Thanks
