Error while running unit tests for CRIU 1.8 - linux

Question

I am trying to run the unit tests on CRIU 1.8. To prep the box, I installed:
libprotobuf-lite8
libprotobuf8
zlib1g-dev
libprotobuf-dev
libprotobuf-c0
libprotobuf-c0-dev
libprotoc8
protobuf-c-compiler
protobuf-compiler
libaio-dev
libcap-dev
After that, as root, I ran, make test and got the following output:
...

make[2]: Leaving directory `/home/ubuntu/criu-1.8/test/zdtm/live'

I assume my issues are the ones inside the CRIU CHECK block there, but I'm just not sure what I am seeing here. Can anyone point me in the right direction. If Google was helpful, then I was just too ignorant to recognize it. Thanks!
Also, I don't have the reputation on SO to tag this as CRIU (apparently that's a new tag), but it is clearly related to CRIU. If you agree and have the power, please throw a tag on this?

You need a new Linux kernel.
The stuff in that CRIU CHECK box is all about things that it requires, but are not supported by either the libraries on your system (e.g. libc), or by the kernel. In the box below, they describe where you'll have to get the kernel that has the necessary patches:

Follow the instructions on the CRIU installation page on how to configure the kernel: https://criu.org/Installation. And, use a page like the one at "kernel newbies" for general advice on building the kernel yourself: http://kernelnewbies.org/KernelBuild.
Building a kernel is fairly straightforward, but it can sometimes be tricky to get it working correctly. Make sure to leave a fallback kernel in GRUB, and consider having some sort of "live" bootable Linux ISO accessible to get back into your system in case it totally goes south.
