Despairing, I purged/autoremoved all of Transmission, and re-installed from scratch. Now I am receiving an even weirder message when I try to access the web interface:
So, what is the deal? How do I solve this? Is there a directory somewhere on my disk that I need to point Transmission to? Is there a phantom package I need to install that includes the web interface files?404: Not Found
Couldn't find Transmission's web interface files!
Users: to tell Transmission where to look, set the TRANSMISSION_WEB_HOME environment variable to the folder where the web interface's index.html is located.
Package Builders: to set a custom default at compile time, #define PACKAGE_DATA_DIR in libtransmission/platform.c or tweak tr_getClutchDir() by hand.
The Transmission wiki helpfully explains "Web interface file locations tend to be OS/Distribution specific."

Any advice or assistance would be much appreciated. Thanks!
