In the end, the update was successful, but the process was a bit

Downloaded R067 firmware to laptop. Checked the checksum, all good. Uploaded to my Almond+. Checksum all good. Proceed to do the update. Waited. Waited. Waited. 30 minutes. Almond+ keeps working. Does not reboot. Wait Wait Wait. Wi-Fi drops, but the Almond+ is still on. Finally I gave up and power cycled my Almond+. Rebooted and all is happy running R067.

Other than a routing hack for Google 8.8.8.8 DNS for Netflix, I have not done any config changes. I do have three ZigBee devices connected.
I guess Lars and his team would be interested if other folks have the similar update
