The major weirdness is the apt does not find the software.
# apt install nut nut-client nut-server
E: Unable to locate package nut
E: Unable to locate package nut-client
E: Unable to locate package nut-server
so how do I get the software from the repository?
I have 2 different upses (same model) to provide some power security for my
various systems.
Which is best practice - - - connect both upses to one system and monitor
from that or is there another option for best practice?
