I'm running Linux Mint 18.2. I've previously had no problems installing or running PoE. I downloaded the 3.07 version of the base game and expansions. Was able to install PoE, White March Part 1 and the Deadfire Pack, but White March Part 2 won't install. When I try to run the install script from the terminal, I get the following:

scott@scott-laptop ~/Downloads $ ./pillars_of_eternity_white_march_part_2_dlc_en_3_07_16404.sh
Verifying archive integrity... All good.

PANIC
Initial setup failed. Cannot continue.

I tried redownloading the DLC and got the same result. Any ideas?

The installer is incomplete
