So I have downloaded installed the core megaavr for the nano everything, I have downloaded and installed the library for the grove TH02 temp sensor. I have successfully compiled my temp warning program and now I am trying to upload it.
First try pointing to port, second attempt point to both port and board fqbn:
robert@mountain-cabin:~$ arduino-cli upload -p /dev/ttyACM0 ~/Arduino/Sketch_Book/temperature_warning/temperature_warning.ino
avrdude: jtagmkII_initialize(): Cannot locate "flash" and "boot" memories in description
robert@mountain-cabin:~$ arduino-cli upload -p /dev/ttyACM0 -b arduino:megaavr:nona4809 ~/Arduino/Sketch_Book/temperature_warning/temperature_warning.ino
avrdude: jtagmkII_initialize(): Cannot locate "flash" and "boot" memories in description
Couple things here, is that a typo, nona4809? Would that by chance supposed to be nano4809?
That is your typo, no mine just so we are clear:
robert@mountain-cabin:~$ arduino-cli board list
Port Type Board Name FQBN Core
/dev/ttyACM0 Serial Port (USB) Arduino Nano Every arduino:megaavr:nona4809 arduino:megaavr
Why is it so hard to find the cli documentation in one place on the arduino website?
Argh, well getting closer and closer with every post. But I have to say, for something that has been around for so long I am baffled by all the bugs and problems I have encountered in my short 10 days of getting my new nano everything board.
Yes, I know if I just ran windows 10 and downloaded the IDE things would be so much smoother, but I am not a vanilla ice cream, I am a multicolored, multiflavored, difficult to manage edge case!
Ok, so I found all the documentation on the github page. Not sure why you don't have it documented on the actual arduino.cc site but oh well nothing I can do about that.
In going through the commands, I got board details, I also did a burn-bootloader -h, config dump and cache -h commands.
Somewhere in that process I must have made it touch itself because it obviously became aware of its new found flash and boot memories...or perhaps not, lol!
I don't have an IDE installed hence the reason I am using the CLI interface. But following your advice I did in fact use the verbose option and low and behold it works all the sudden, lol

Actually I do notice a couple things here that are warnings/errors but not enough to stop the process..
I noticed config file missing error in the output I listed above so I ran arduino-cli config init to generate a config file and ran the upload again.
robert@mountain-cabin:~/Arduino$ arduino-cli config init
Config file written to: /home/robert/.arduino15/arduino-cli.yaml
User configuration file is "/home/robert/.avrduderc"
User configuration file does not exist or is not a regular file, skipping
Error #2 is the original error I that started this thread, not sure why all the sudden it is not a problem where as it was before??

You can ignore that warning, it is always shown when uploading a sketch to a nano every using the IDE, so it is not surprising to see it using the CLI.
I guess it's a bit of an easter egg from the boards platform developers.
You're welcome to submit reports for any bugs you have found.
This is normal and expected. Please just ignore it. The AVRDUDE uploader tool used for the Nano Every has a capability to use a global configuration file. That is convenient for people who are using AVRDUDE directly. But with Arduino boards platforms, they configuration file is bundled with the tool installation, and the path to that file specified via the upload command. So it is perfectly fine if you don't have a global user configuration file.
You're falling into the common pitfall of interpreting innocuous informational messages or warnings as errors. It's good to pay attention to these, and do some research about what they mean if you're curious, but don't assume they mean something is wrong. In general, if you are getting an exit status 0 and everything is working as expected, then it's fine.
