384.98-2 dropped into sid this morning. It installed.
This last weekend, I purged nvidia, and reinstalled. What was available in sid was 375.82, and it stalled. Then 378 came into sid, and it was installable. Then this morning, I was able to install 384.98-2.
Still having a mesa-related error:
root@asus:/home/chris# glxinfo | grep OpenGL
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request: GLXBadContext
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 6 (X_GLXIsDirect)
Serial number of failed request: 48
Current serial number in output stream: 47

But that's another issue that I'm hoping a mesa update will fix. The installation issue is resolved for me.
