My Canon 700D CR2 files show up in Darktable's lighttable view, but when I select one and open it in darkroom, Darktable says the image is "currently unavailable." I'm using Darktable on Ubuntu MATE 18.04 on an ASUS X550 with 12GB RAM. I checked file permissions and the CR2 files appear readable and writable. What causes this message, and how can I fix it?

Darktable does not "import" images. It remembers them, their file location and their thumbnail. However, to do anything with them, the file actually needs to be present at the expected location, typically by plugging the memory card into a reader or connecting the camera with a USB cable. If it isn't, you get that error message.

This usually means Darktable can see the thumbnail and remembers the photo entry, but the original RAW file is not available at the path where Darktable expects it.
Darktable does not truly import images into its library. It stores references to the files, their locations, and thumbnails. If the original CR2 file has been moved, renamed, disconnected, or is still on a memory card/camera that is no longer connected, Lighttable may still show it, but Darkroom cannot open it.
What to check:
- Make sure the memory card or camera is connected if the files were never copied locally.
- Confirm the CR2 files still exist in the same folder and path.
- Check that the folder/mount point is available.
- If files were moved, re-add them from their current location.
So the issue is most likely file location/availability rather than RAM or basic file permissions.
