Ok, thanks a bunch!  Finally able to get some software response. 
Initially I tried just clicking on the deb and installed from the 
software center, but wasn't getting any of the above.

I recently had to replace the power supply so it's about double what the 
UPS is supposed to handle.  After about 2 min, batt had dropped to 35%, 
so will have to be sure and shut down asap if power fails.

Thanks again for your help.  I will print out the instructions and keep 
them handy nearby.
