I have tested this on my Disco development machine, and here's what I found.
Using an iPhone SE running IOS 12.1.2. Connected the phone using a real cable (using my third party cable only allowed me to charge). Without doing anything further I open Nautilus and browsed to the phone, and indeed I did see the error described... "unhandled lock down". However, on the phone itself I was being asked if I wanted to "Trust this computer". I said "Trust this computer" and was then asked to enter my PIN. Once I had done this I was able to browse the photos as expected. Could people reporting this problem please check that the iDevice has been told to trust the computer and comment here? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to libimobiledevice in Ubuntu. https://bugs.launchpad.net/bugs/1799913 Title: Unhandled lockdown error (-2) - iphone ios 12 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libimobiledevice/+bug/1799913/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
