Install Sphinx in Debian 8 with Mariadb

Hello, i'm trying to install sphinx on debian 8

I tried to follow this guide on mariadb site

https://mariadb.com/kb/en/mariadb/installing-sphinx/

I installed

sudo apt-get install software-properties-common python-software-properties

then:

sudo add-apt-repository ppa:builds/sphinxsearch-rel21

But when I try to:

sudo apt-get update

I get the following error:

Err http://ppa.launchpad.net jessie/main amd64 Packages

404 Not Found

Ign http://ppa.launchpad.net jessie/main Translation-en

Fetched 872 B in 1s (466 B/s)

W: Failed to fetch http://ppa.launchpad.net/builds/sphinxs … 4/Packages">http://ppa.launchpad.net/builds/sphinxsearch-rel21/ubuntu/dists/jessie/main/binary-amd64/Packages 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

I tried to ignore this error and continue doing:

sudo apt-get install sphinxsearch

But I get these error:

Reading package lists… Done

Building dependency tree

Reading state information… Done

E: Unable to locate package sphinxsearch

Does anyone know how to install sphinx on debian 8 with mariadb? Any tips will help.

Thank you.
