Cannot update indexes - Upload

[mpkennedy58]

Please help.

This is what is in the “extra.txt” file: http://arduino.esp8266.com/stable/package_esp8266com_index.json,https://dl.espressif.com/dl/package_esp32_index.json

Is there something wrong with this? Please help…

I am using version 0.38

You will receive that error if both board definitions are on the same line, separated by a comma:

http://arduino.esp8266.com/stable/package_esp8266com_index.json,https://dl.espressif.com/dl/package_esp32_index.json

The board definitions should be on separate lines:

http://arduino.esp8266.com/stable/package_esp8266com_index.json
