Sorry to reply to myself. Hearing from no one for almost a week, I decided to "check around" again and see if I couldn't find some way to restore Google Chrome ...
This posting gave me the idea to "downgrade" the application: http://goo.gl/I5chaZ Looking in my system's /var/cache/apt/archives', I found all recent upgrades to google-chrome-stable. I decided to re-install the previous update version: google-chrome-stable_49.0.2623.75-1_amd64.deb I then attempted to apply the package using this: # dpkg -i google-chrome-stable_49.0.2623.75-1_amd64.deb That produced an error message: > > Package libappindicator1 is not installed > Went back into 'aptitude', and installed 'libappindicator1' and its required dependencies. Finally, I ran the 'dpkg' command above once again, and *BINGO* ... success! Maybe this might help someone else ... :) -Kenneth
