Issue Description

After following the installation instructions found at https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md
for my Ubuntu 16.04 PC it failed to patch the uvcvideo module.

The first that I could not do was the specific to Ubuntu 16 command:

Ubuntu 16:
sudo apt-get install cmake3 libglfw3-dev

It could not find cmake3, I have cmake I hope that is good enough.

And then it failed in the command:

./scripts/patch-realsense-ubuntu-lts.sh

Output:

Package required libusb-1.0-0-dev: - found
Package required libssl-dev: - found

Should I use an older commit?

Ubuntu 16.04 recently updated the version of the HWE kernel to 4.15. That's why the patch fails. I manually downloaded the sources for the latest 4.13 HWE and manually applied the patches. Then I modified the script to skip downloading kernel sources and applying patches.

thanks for your help @abecciu.

hi @angeltop,
would like to know if abecciu's suggestion solve your issue?

@abecciu would you please give more details about "downloaded the sources for the latest 4.13 HWE and manually applied the patches" and "modified the script to skip downloading kernel sources and applying patches" , thanks a lot!

[angeltop]

Dear @abecciu thank you very much for your reply. I would really appreciated, if you could give some instructions on how I could do it manually for 4.13 and the modified lines of the script "scripts/patch-realsense-ubuntu-lts.sh". Otherwise, I will wait a few days or weeks for kernel and uvcvideo patch to be at the same version.

@angeltop ,@TonyFaith,
The patches for Ubuntu HWE with 4.13 have been updated in the latest version available on github.
See the PR link posted above for details.

Please give it a try and update.
