i'm trying connect webcam logitech c170 raspberry pi board , use raspistill command. somehow not work. i'm getting following error.

i've tried updating rpi, updating , upgrading apt-get, enabled camera option in raspi-config. nothing seems work. please help.

the raspistill command used raspberry pi camera module. webcams, use fswebcam - https://www.raspberrypi.org/documentation/usage/webcams/ useful reference. trying use mjpg-streamer? if raspistill not - capture still image , save pi. use mjpg-streamer command - see http://www.justrobots.net/?p=97 more details.
