Hi Radek,
Thanks for fast answer.
From INDI control panel I got this after I power down the camera and then power it on again:
2020-03-01T10:42:58: [ERROR] Can not open camera: Power OK? If camera is auto-mounted as external disk storage, please unmount it and disable auto-mount.
2020-03-01T10:42:58: [ERROR] Camera_get_config failed (-2): Bad parameters
2020-03-01T10:42:56: [INFO] Canon DSLR EOS 6D is offline.
2020-03-01T10:42:22: [INFO] World Coordinate System is enabled.
To open the terminal I start VNC and connect to Raspberry, use the LX terminal, run the 'mount' command and got this:

I can't see that the Canon is mounted, or ?
After that I tried the command you gave me (two different and maybe umount shall be unmount ?):
astroberry@astroberry:~ $ umount path_to_canon_dev
umount: path_to_canon_dev: Filen eller katalogen finns inte
astroberry@astroberry:~ $ unmount path_to_canon_dev
bash: unmount: kommandot finns inte
astroberry@astroberry:~ $ umount/dev/sda1
bash: umount/dev/sda1: Filen eller katalogen finns inte
astroberry@astroberry:~ $ unmount/dev/sda1
bash: unmount/dev/sda1: Filen eller katalogen finns inte
I got the answer that the command doesn't exist.
By the way, when I setup Astroberry I have to set Swedish language because I live in Sweden. I want English but then I couldn't choose Swedish keyboard layout. In the older Ubuntu Mate I could have Swedish layout on the keyboard and English text in Ubuntu mate. Is there a fix to this problem ? It's a bit confusing when I send the log to others who doesn't understand Swedish.
Thanks for all help !
