Linux installation instructions do not seem identical in different documents.

[JBirk]

The instructions for a Linux installation do not seem identical in the following three documents.

Please clarify why all three of these directions are not identical and provide guidance as to which instructions to use.

*******************

In this document https://realsense.intel.com/sdk-2/#install , 

the following Linux installation instructions are provided:

Add Intel server to the list of repositories :

echo 'deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo xenial main' | sudo tee /etc/apt/sources.list.d/realsense-public.list

It is recommended to backup /etc/apt/sources.list.d/realsense-public.list file in case of an upgrade.

Register the server’s public key :

sudo apt-key adv --keyserver keys.gnupg.net --recv-key 6F3EFCDE

********************

In this document https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md , 

the following Linux installation instrucitons are provided:

Register the server's public key :

sudo apt-key adv --keyserver keys.gnupg.net --recv-key C8B3A55A6F3EFCDE || sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key C8B3A55A6F3EFCDE

In case the public key still cannot be retrieved, check and specify proxy settings: export http_proxy="http://<proxy>:<port>"

, and rerun the command. See additional methods in the following link.

Add the server to the list of repositories :

Ubuntu 16 LTS:

sudo add-apt-repository "deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo xenial main" -u

Ubuntu 18 LTS:

sudo add-apt-repository "deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo bionic main" -u

When upgrading, remove the old records:

sudo rm -f /etc/apt/sources.list.d/realsense-public.list.

***********************

 In the following document, the instructions are below.

https://www.intel.com/content/dam/support/us/en/documents/emerging-technologies/intel-realsense-technology/Intel-RealSense-SDK2-Github-Guide.pdf

• Add Intel server to the list of repositories:

echo 'deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo xenial

main' | sudo tee /etc/apt/sources.list.d/realsense-public.list

It is recommended to backup /etc/apt/sources.list.d/realsense-public.list file in case

of an upgrade

• Register the server's public key:

sudo apt-key adv --keyserver keys.gnupg.net --recv-key 6F3EFCDE

[MartyG]

It looks like sources 1 and 3 are identical, and just look different because they are presented in very different visual formats (the blue background of 1 can throw off the eye compared to the white background of 3).

I believe link 2 describes the process for setting up Librealsense using pre-built packages instead of compiling them from source.

[JBirk]

Link 2 states "We strongly recommend to use DKMS package whenever possible" So I guess Link 2 is the process to follow, despite two other prominent web sites that offer other directions.

During the link 2 process, is there ever a time to download and extract the source code, or do the pre-built packages include the source?

[JBirk]

Once again, do the pre-built packages include the source from https://github.com/IntelRealSense/librealsense/releases ?

[MartyG]

Pre-built binaries and source are usually kept separate. On the bottom of the Linux Distribution page, it states "The packages include binaries and configuration files only. Use the github repository to obtain the source code".

[JBirk]

I assume with the "packages" and the "source code" that the installation would be complete. I hope there isn't a third leg to the stool that customers have to find somewhere.

Marty - Thanks very much for your help. It is really appreciated.
