result in "E: Unable to locate package cheerp-core" with my vps when trying to install cheerp with PPA

I've followed the guide from "https://github.com/leaningtech/cheerp-wiki/wiki/Ubuntu-Debian-installation-using-PPA", the title said:
"Ubuntu Debian installation using PPA"

the following is the whole process with putty on my debian VPS:

root@www:~# nano /etc/apt/sources.list
                  (deb http://ppa.launchpad.net/leaningtech-dev/cheerp-ppa/ubuntu trusty main
                   deb-src http://ppa.launchpad.net/leaningtech-dev/cheerp-ppa/ubuntu trusty main)
                I appended the above 2 lines on the sources.list file

Debian stable is not supported, you need to use debian testing (jessie). You also need to run 'apt-get update' after adding the repository and the key. The guide on the wiki is now fixed:
