Okay, gave up on this since I needed an operational image server to finish deploying PCs that replaced the last of our XP boxes. Uninstalled Fog on 14.04 following these instructions ([B]excluding[/B] the removal of the /images directory):

Re-installed Fog 1.2.0 on same Ubuntu 14.04 server. Existing images from old Fog server still in /images. I opted not to try to import anything else from the old Fog 0.32 server. Created new image entries and assigned the corresponding image file names. I did a trial run by uploading an image from a Dell OptiPlex 390 with some success. Will be testing more today for functionality and stability.
