Hi,
I'm seeing the following problems when building librealsense-2.14.0 on a fresh Ubuntu 18 machine:
~/Src/RealSense$ uname -r
4.15.0-29-generic
Errors:
~/Src/RealSense$ sudo apt install libgtk-3-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libgtk-3-dev : Depends: libgdk-pixbuf2.0-dev (>= 2.30.0) but it is not going to be installed
Depends: libpango1.0-dev (>= 1.40.5) but it is not going to be installed
Depends: libcairo2-dev (>= 1.14.0) but it is not going to be installed
Depends: libfontconfig1-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
And:
~/Src/RealSense$ sudo apt install libssl-dev

Any advice greatly appreciated!! Thanks!

It seems to be a Linux error rather than a Librealsense-specific one. The guide linked to below looks useful.

Hi Marty! Thanks for the link. My concern is that, given the problem with Ubuntu, the build and installation instructions are now in error.
An updated build and installation instructions would be most appreciated that accounts for this problem.
Thanks!

I've seen enough successful builds of 2.14.0 to make me think that the issue is likely not in the build instructions. The best place to ask this question may be the Librealsense GitHub page, as they deal with these kind of installation questions all the time. You can do so by visiting the link below and clicking the 'New Issue' button.

Posted to GITHUB per MartyG's suggestion, here should anyone else have this problem:
https://github.com/IntelRealSense/librealsense/issues/2134 Ubuntu 18.04 build issue with libgtk-3-dev & libssl-dev on D435 libRS 2.14.0 · Issue # 2134 · IntelRealSense/librealsense…
I'll note that we have other Ubuntu 18.04 machines (they were built a few weeks back and are running libRS 2.11), and this problem occurred this time when we built our most recent machine (from a fresh/blank drive). It's probably a timing issue where Ubuntu is in a bad state, but, nevertheless, it is presenting a problem for us to move forward with additional developer machines.

Hello SMM77,
We noticed that your ticket on GitHub has been updated with the following suggested solution:
It seem that the distribution has some missing/broken packages.
You can run dpkg -l | grep ^..r to list those, and then use Ubuntu tools to rectify it
sudo apt update --fix-missing and
sudo apt install -f
Please let us know if this solved your issue.
Regards,
Jesus G.
