I have a pretty stock ubuntu-18.04 desktop that's run makemkv with no problem before. I noticed the new version (1.14.2), followed the install directions:
sudo apt-get install build-essential pkg-config libc6-dev libssl-dev libexpat1-dev libavcodec-dev libgl1-mesa-dev libqt4-dev zlib1g-dev
cd makemkv-oss-1.14.2
./configure
make
sudo make install
cd ../makemkv-bin-1.14.2
make
sudo make install

Now when I try to use it I get:

Saving 4 titles into directory /home/bill/Videos/ABC
Unable to execute external program 'ccextractor' as its path is not set in preferences
Failed to execute external program 'ccextractor' from location '/usr/bin/mmccextr'

I searched my drive and neither the ccextractor nor mmccextr

Ah, turns out there's a line under each title you select that says something like CC => lossy compression or similar. If you uncheck it, it works.

It also seems to work to provide a dummy script which returns success.

I created "/home/<myuser>/bin/ccextractor.sh" with

#!/bin/bash
exit 0

in it, chmod +x -ed it, and pointed MakeMKV to it. Now the default option to extract works, but doesn't waste time actually extracting.
