Install sudo apt install dcraw
Description:

This utility converts the native (RAW), format of various digital cameras into netpbm portable pixmap (.ppm) image. Supports the following models: Canon, Kodak, Olympus, Nikon, Fuji, Minolta and Sigma (see http://www.cybercom.net/~dcoffin/dcraw/ for full list) Note: This utility does not read directly from the cameras, only the files after they have been downloaded, use gphoto2 for that.
