Transfering photos and videos from iphone to linux mint desktop

I am trying to transfer all my photos and videos from the iphone to my linux mint desktop but when I connect my phone I get a message which says 'Unable to mount documents on iphone, unhandled lockdown error (-21)
Anyone knows what’s that?
Thank you.

Possibly KDE connect would be a solution. I see that it is available in the Apple Store and should be in Mints repos as well.

And the connection may need to be OK’d on the iPhone.
