Ubuntu 16.04 x64 and Linuxcnc 2.8.0 / 2.7.7 was created by hainjedaf
Hi,
I am reasonably new to the linuxcnc thing. I had a working config using the linuxcnc install and wanted to move up.
I installed ubuntu 16.04 with latest upgrades and all necessities for building linuxcnc.
Linuxcnc builds both in 2.7.7 and 2.8.0-pre1 (master) branches
Latency-test produces figures sub 25000 so acceptable for my mesa 5i25+7i76 setup.
When starting linuxcnc both versions fail when loading the XHC HB04 pendant modules.
No useful info is printed in Linuxcnc_debug.txt
dmesg provides following:
where am I going wrong or do I have a bug at hand?

It's the import vte line that goes wrong.
sudo apt-get install python-vte
You likely will get a number of those messages of missing modules and you need to install them.

Sorry for the short reply yesterday, it was late and I wrote on the ipad.
There may be more to it than I realized yesterday.
I built linuxcnc a few days ago and came across exactly the same messages, modules missing.
It was just to follow instructions to be be able to build linuxcnc.
But to get gmoccapy running I had to install a number of python packages.
The shut down message was exactly the one shown here with import module
failing. After starting/installing about ten times it all started up.
I would say fix all the missing modules first, they should be easy to install.
Hopefully what you see with xhc-hb04 is then gone.
I don't know anything specifically about ubuntu, I am on debian wheezy.
Kernel is 4.4 something with rt-preempt patches.

First time I started linuxcnc from master (2.8-pre) with an old ini file I was offered to convert the ini file to the new format where axis and joints are separated. Accepted, and it worked after that. There were some almost trivial name changes needed in the hal files as well.
Just for the sake of testing, I installed ubuntu 16.04 in a virtualbox computer and built linuxcnc. It can absolutely be done.
The first problem was that instructions for "fulfilling dependencies" from the README didn't work. But ./configure gave me a lot of clues and I had to guess some but it was all a matter of installing a number of packages. After ./configure finished I ran "make" successfully, one warning I think.
To run linuxcnc it was again a matter of installing a number modules and libraries. Clues are given by the shutdown messages from the linuxcnc command, and later by pop-up windows. Also the python-vte mentioned in the first post showed up. The trickiest was the last error about "playbin" which was resolved by installing gstreamer0.10-plugins-base. Right now I have gmoccapy running in the sim ina virtualbox.

Thanks to you all, but Hakan's reply nailed it.
The PLAYBIN error got me up the wall but his answer made it a home run.
I now have:
-Ubuntu 16.04.02 LTS x86_64
-Kernel 4.8.6-RT5+ (built as debian packages)
-LinuxCNC 2.8.0-pre1
THanks!!

-Download latest RT-kernel patches
-Download kernel source to to fit patches.
-Unpack kernel in /opt/kernel-x.y.z-rtAB depending on rt patch number
-Patch kernel with RT-patches.
-Install build-essential.
-Configure kernel to enable 'FULL PRE-EMPTIVE RT' (make menuconfig)
-Compile the kernel and build a debian kernel package
-Install kernel using dpkg -i kernel-x.y.z-rtAB.deb
-follow instructions on building linuxcnc: linuxcnc.org/docs/devel/html/code/building-linuxcnc.html
-carefully read errors when linuxcnc fails or crashes to determine packages needed.
-install missing packages
-retry and repeat until linuxcnc starts
Hakan gave a valuable tip because that 'playbin' thing does not immediately point at gstreamer.

New to Linux as a whole, but I'm having a bunch of trouble with this set up. I've installed Ubuntu 16.04.4, and I've tried a range of different ways to install 2.7. LiveUSB, in terminal, LiveCD, LiveInstall, and literally none of them work. Did you figure it out? What can I do differently?
