On update, error with local repository

I'm running PiHole on a Raspberry Pi 2 under DietPi v159 (the latest DietPi release.) I went to update PiHole on 31 Dec 2017 and received the following error:

Error: Could not update local repository. Contact support.

Unable to complete update, please contact Pi-hole Support

My PiHole installation is fairly vanilla; all I have done is added the repository "https://v.firebog.net/hosts/AdguardDNS.txt" to the block lists. Any idea on how to address this error?


What is the output of

cd /var/www/html/admin;git status 
cd /etc/.pihole;git status 



Wonderful, how have showed me how to do the update properly.

showed all kinds of modified issues, as follows:

pi@atlantis:/etc/.pihole $ cd /var/www/html/admin;git status

I followed the suggestions in the following website to address these modifications prior to the update:

I also saved the lighttpd.conf file as suggested on the DietPi forum website:

And once I did so the update worked great.

Thanks for the help.
