As here explained, that the Ubuntu versions of Multimarkdown are broken.
The result is, that you can't export Scrievener documents into Latex documents, because the compiling process breaks with a unknown error.

With that steps i have fixed it, so i can export to Latex:

• sudo apt - get purge libtext - multimarkdown - perl

• sudo apt - get install cmake checkinstall

• git clone https://github.com/fletcher/MultiMarkdown-5.git 

•  cd into the checked out repository 

• ./ link_git_modules

• ./ update_git_modules

•  make 

•  cd build 

•  make

•  make test 

•  checkinstall 

The 'make test' command should fail with one test.Additional documents about checkinstall you can get there .More about the Scrievener Latex - Configuration is available there .
