Public bug reported: Upon upgrading from 16.04 (xenial) to 16.10 (yakkety), at some point (it was difficult to tell at what point, since due to another bug with the system fonts(?) the system fonts were unreadable blocks. That issue went away), after the packages were mostly installed, the wireless network indicator in gnome disappeared, and my connection to the internet was lost. Attempting to get a connection via wicd-curses resulted in -
ERROR:connection_factory_impl.cc(369) Failed to connect to MCS endpoint with error -137 errors when an attempt was made to get an IP address.

Rebooting system post-install -> worked just fine, wireless indicator was there upon login again as usual.
