Only recently when I tried to import my Canon 700D CR2 photos, they appear in the lighttable section but when I select and click darkroom I receive an "....image is currently unavailable".
I'm running Darktable on a ASUS x550 with 12Gb RAM on Ubuntu Mate 18.04. I checked permissions on all CR2 images and ALL are set to full "rxw".
I'd really appreciate some help. Hal
