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 root@asus:/home/chris# glxinfo | grep rendering 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 root@asus:/home/chris# But that's another issue that I'm hoping a mesa update will fix. The installation issue is resolved for me.
