Permission Denied Error

Hello

only just installed Arduino IDE and I keep getting this error when uploading/verifying my code in the console:

fork/exec /root/.arduino15/packages/esp8266/hardware/esp8266/2.5.0-beta1/tools/signing.py: permission denied Error compiling for board SparkFun ESP8266 Thing.

Here is the Error Message that I copied from log: Arduino: 1.8.8 (Linux), Board: "SparkFun ESP8266 Thing, 80 MHz, Flash, Enabled, 512K (no SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

fork/exec /root/.arduino15/packages/esp8266/hardware/esp8266/2.5.0-beta1/tools/signing.py: permission denied Error compiling for board SparkFun ESP8266 Thing.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

I've done loads of research and I cant find any answers! Please can someone help? Thank you! :)
