installing PCL

edit

Hello, i'm trying to install the PCL library but i'm facing a little problems.I followed this link http://www.pointclouds.org/downloads/... but when i try the first command

sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl

and then

sudo apt-get update

i got this

Reading package lists... Done
W: The repository 'http://ppa.launchpad.net/v-launchpad-jochen-sprickerhof-de/pcl/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/v-launchpad-jochen-sprickerhof-de/pcl/ubuntu/dists/xenial/main/binary-amd64/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

so when i run the third command

sudo apt-get install libpcl-all

i got this

Reading package lists... Done
Building dependency tree

E: Unable to locate package libpcl-all

and when i try the Debian install i face the same problem, i think the package maybe moved to a different repository. i'm using Kinetic-kame ubuntu 16 thanks in advance
