I'm new to Darktable on Ubuntu and can't import photos directly from my Canon R5 over USB. The camera appears in Darktable's import pane, but when I click "mount camera" I get an error like: "failed to initialise 'Canon R5' on port 'usb:001,009' likely causes are: locked by another application, no access to devices etc." If I switch the camera off it disappears from the import pane, so the system does see it. What causes this, and how can I import successfully?

Tried connecting camera without Darktable running and noticed that two instances were showing as mounted. I clicked on one unmount icon, both icons disappeared. I then started Darktable and clicked on mount. Simple when you know how, shame it doesn't mention this in the manual.

This usually happens because Ubuntu has already auto-mounted the camera, so Darktable can't claim the device. One user found that the camera appeared as two mounted items in the system; after unmounting them, Darktable was able to mount the Canon R5 normally.
Try this:
- Quit Darktable.
- Connect the camera.
- Check your desktop/file manager for any auto-mounted camera/device entries.
- Unmount/eject all of them.
- Start Darktable and try "mount camera" again.
If that still feels unreliable, a simpler workflow is to avoid importing directly from the camera: remove the memory card and use a dedicated card reader, then copy files to your computer and import them into Darktable from there. That's often faster and avoids USB/PTP mounting conflicts entirely.
