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 .
