I'm using a Nikon Coolpix S4300 camera, Shotwell Photo Editor, Ubuntu Mate 20.04.
This morning I tried to download a few photos from the Coolpix camera. This camera used to work perfectly every time I downloaded in the past. I got the message that "the camera is locked by another application ".
I have tried everything I could think of: removing the battery, shutting down the computer and rebooting, removing all cashe and cookies, etc. To download I am using the OEM USB cord. Always worked in the past.
Any ideas on what to do?
