Nikon camera is locked out...

Asked by Ralph Martin


Using Ubuntu Mate 20.04 - Shotwell was working fine the other day, when downloading photos from camera.
Using: Nikon Coolpix S4300

When I open Shotwell on my computer to transfer pictures in the screen shows this : The camera is locked by another application. Shotwell can only access the camera when it's unlocked. Please close any other application using the camera and try again. Id like to know how to find this other application and kill it or know what I doing wrong.

I had a power outage the other day and my printers didn't work right. That was fixed. Not sure if the power outage had any thing to do with this.

The link to the camera might be /dev/video0 and the application locking it can probably be found out with the command

sudo fuser /dev/video0

If this does not help, you might reboot your computer. That should free up the resource.

Hi Manford

sudo fuser /dev/video0 = Specified filename /dev/video0 does not exist.

These are still photos, just saying.

If you know (or can find out) what the device name for the camera is, then you can try freeing the device with the fuser command.
In any case a reboot should help.

Hi Manfred,

I'm tired of screwing around with this issue. I'm old and frustrated. Doesn't take much anymore. Also I'm not as geeky as I would like to be.

I am just going to take the SD card out and download the photos that way.

Nothing seems easy anymore for me.

Thank You for your time in this matter, it's well appreciated.
