  Hello All,
  
  I am trying to install EnviroDIY ATmega Boards in my Arduino IDE and I keep getting the same error message.
  
  Error: 2 UNKNOWN: installing platform EnviroDIY:avr@1.0.0: testing local archive integrity: testing archive size: fetched archive size differs from size specified in index
  
  I have installed all the necessary libraries and I can’t seem to fix the error.

  Are you following the instructions from the top of this page to add the Mayfly board to your IDE: https://www.envirodiy.org/mayfly/software/
  
  You should be able to copy-and-past the URL of the json file into the appropriate place in the IDE Preference window and then the IDE will fetch the file and load it properly. We haven’t made any changes to the board definition files in several years, so there shouldn’t be any problems. What version of the Arduino IDE are you using?

  Thank you for your reply.
  
  I am following the instructions point to point. I was able to copy-paste the URL but I keep getting the same error. I use Arduino IDE 2.0.0-beta 4.

  The Arduino IDE 2.0 is still a beta release and is so new that we haven’t done extensive testing to make sure all our EnviroDIY-related instructions, libraries, and sketches work perfectly. So I would recommend you use the regular release of version 1.8.13 (available here: https://www.arduino.cc/en/software) instead of the beta version.
