[nmglug] mint 20 shutting down

[Aaron Birenboim]

I have a new, clean,  Mint 20 install which is shutting down after long 
periods of non-use... like 6-10 hours.  I have tried many things to 
disable this.

I have peeked at logs, but nothing is jumping out at me.  How can I find 
out why the machine is shutting down?

Sure, a wake-on-lan/ssh would be fine for this machine, but I'll worry 
about that after I can figure out how to keep it up.

I had it running 24/7, months at a time under Mint 18.
