So I'm running Linux Mint 18.3 XFCE 64-bit, and I was able to install Morrowind and Tribunal from my retail copies of the discs, but when I try to plop in and install Bloodmoon it fails with an "Unable to Extract Morrowind.bsa" and it points to /home/[MyUsername]/.local/share/openmw/basedata/extract-temp/Bloodmoon/Morrowind.bsa
Now at the moment instead of trying to install them all in one go, I had to do em separately because of how the install wizard was trying to read the CDs
Did a misread a step?
I am using OpenMW 0.44.0
EDIT:
I just ended up installing Morrowind through WINE and linking OpenMW to those files
