GitLab

as explained in #81:

  It says all packages were downloaded:

    Updating index: package_index.json downloaded
    Updating index: package_esp8266com_index.json downloaded
    Updating index: package_lalala_index.json downloaded

  But when you run commands like arduino-cli core list or arduino-cli board listall it exits with an error:

    Error: loading json index file /Users/MY_USER_NAME/arduino-cli/data/package_lalala_index.json: invalid character '<' looking for beginning of value
    Failed to load http://google.com/package_lalala_index.json package index.
    Try updating all indexes with `arduino-cli core update-index`.

  It occurs, because package_lalala_index.json contains 404 HTML page.
