The compute stick ( https://www.amazon.com/Intel-Corp-BOXSTCK1A8LFC-Compute-STCK1A8LFC/dp/B00W7KAABK [ Amazon link to Intel “compute stick” with Ubuntu 14.04 ] ) ran out of space during the upgrade to 16.04, so I will set it aside for a later date instead of rushing out and buying a USB hub and external storage for one-time use at the hotel.
