iPhone仅安装一次，不显示图片，重新安装文件
我有一个最初通过USB连接的iPhone 8，因此图片和文档文件夹在Ubuntu 17.10下可用。 但是，这在Ubuntu重新启动之间只能运行一次。
我该如何解决这个问题？
这必须是一个错误或配置问题，而不是一些软件丢失或完全不存在，因为它实际上在重新启动后第一次工作。
会发生什么情况是，如果我再次断开并连接iPhone，文件夹图片不会再次出现在“文件”应用程序中。 文件夹Documents会在第二次重新连接时出现，但在第三次重新连接时不会出现。 我没有在dmesg中看到任何错误。
我看到它通过USB识别
[234230.482987] usb 1-1: USB disconnect, device number 6 [234250.239084] usb 1-1: new high-speed USB device number 7 using xhci_hcd [234250.385353] usb 1-1: New USB device found, idVendor=05ac, idProduct=12a8 [234250.385358] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [234250.385362] usb 1-1: Product: iPhone [234250.385365] usb 1-1: Manufacturer: Apple Inc.

我已经检查过这个post如何在Ubuntu 17.04上访问iOS相机图片？ 并运行
idevicepair validate
明白啦：
错误：设备返回未处理的错误代码“-3”
跑这个
idevicepair unpair && idevicepair pair
并且在输入我的iPhone密码后能够成功重新validation，但文件夹不会重新出现。
经过另一次重新连接，我看到了这一点
idevicepair validate
没有找到设备，是否已插入？
试图通过文件应用程序中的afc：// SerialNumber模式访问它告诉我
libimobiledevice错误：未找到设备。 确保usbmuxd设置正确。

现在安装并显示文件夹Documents，但不显示图片 。
在重新连接时，我收到此错误消息弹出对话框（来自Files？）
无法打开iPhone缓存上的文档文件夹无效，重试（内部处理）

但现在afc：//开始工作，我终于可以看到文件夹中的文件夹了：
AirFair DCIM iTunesRestore PhotoData Purchases Books Downloads LoFiCloudAssets Photos Radio CloudAssets iTunes_Control MediaAnalysis PublicStaging Recordings
因此，我似乎有一个访问Photos文件夹的解决方法。 很明显，我希望它能在没有sudo离合器的情况下工作。
升级usbmuxd解决了这个问题。 我从https://packages.ubuntu.com/cosmic/usbmuxd(1.1.1~git20180428.b95a0a0-1 ）下载了一个较新的软件包并安装了它。 令人惊讶的是，它与Ubuntu 18.04兼容。
