SPIFFS Upload Does not complete on Ubuntu

[rupin]

I have an Arduino Folder unzipped and installed on Ubuntu. I am able to run and upload programs using the Arduino IDE.

I am using WifiManager and Need to upload a config file into the SPIFFS. I created a data directory, then copied the ESP8266FS tool as recommended.

Here is the log from the IDE

SPIFFS Upload failed!


Why does the upload fail for the SPIFFS, but the ones for the sketch does not?
