Traceback (last last call): Adafruit BME 280 Sensor

Question

I successfully installed the Adafruit_Gpio package, and when I try to run the bme sensor sample file provided by adafruit, I get the following error:

Traceback (most recent call last): File "/home/rpi3/Adafruit_Python_BME280/example.py", line 3, in <module> sensor = BME280(mode=BME280_OSAMPLE_8) File "/home/rpi3/Adafruit_Python_BME280/Adafruit_BME280.py", line 88, in __init__ self._device = i2c.get_i2c_device(address, **kwargs) File "/usr/local/lib/python3.5/dist-packages/Adafruit_GPIO-1.0.3-py3.5.egg/Adafruit_GPIO/I2C.py", line 64, in get_i2c_device return Device(address, busnum, i2c_interface, **kwargs) File "/usr/local/lib/python3.5/dist-packages/Adafruit_GPIO-1.0.3-py3.5.egg/Adafruit_GPIO/I2C.py", line 97, in __init__ self._bus = Adafruit_PureIO.smbus.SMBus(busnum) File "/usr/local/lib/python3.5/dist-packages/Adafruit_PureIO/smbus.py", line 97, in __init__ self.open(bus) File "/usr/local/lib/python3.5/dist-packages/Adafruit_PureIO/smbus.py", line 122, in open self._device = open('/dev/i2c-{0}'.format(bus), 'r+b', buffering=0) FileNotFoundError: [Errno 2] No such file or directory: '/dev/i2c-1' 

I am on xubuntu for rpi-3, I ran apt-get udpate and restarted the machine without working.

sudo raspi-config

Select:

3 Interfacing Options

Select:
