今天在我的笔记本电脑的第二个分区上安装了 Ubuntu 20.04。不幸的是，我的蓝牙突然停止了服务，无法连接到我的鼠标和键盘。我在这里尝试过，还尝试重新安装 blueman。我尝试连接终端并执行以下步骤：

bluetoothctl
default-agent
pairable on
devices
trust CA:49:A5:2B:02:C4
pair CA:49:A5:2B:02:C4

我收到此错误... 无法配对：org.bluez.Error.AuthenticationRejected

此外，如果我想通过 wifi 图标旁边右上角的蓝牙图标访问蓝牙模块。我收到此错误： blueman-assistant 在回调（）中出现 blueman.bluez.errors.DBusInProgressError 崩溃：操作已在进行中

我希望你能帮助我，当然提前非常感谢你！

背景/用例

我用我的安卓手机拍摄了 24 份纸质文件。每张照片大约 8MB（我打算稍后调整它们的大小）。

我在我的图库应用程序中标记了所有这些，并使用“共享->蓝牙”将它们发送到我的 Linux (Ubuntu Mate) 计算机。

我认为 Linux 端的工具是“blueman”。

问题

在我的 Linux 机器上：

  • 我必须分别为每个文件单击“接受”。
  • 我必须等到一个文件事务完成，才能接受下一个文件。
  • 如果我花太多时间来接受其中一个文件，整个操作就会失败。

这是对时间和注意力的巨大浪费。

问题

有没有办法自动接受来自特定设备或来自同一事务的所有文件？

我的系统

Ubuntu 18.04.3 LTS（仿生）
发行版：Ubuntu Mate
桌面：Mate
无虚拟化

我找不到要连接的蓝牙设备，因此blueman无法正常工作，我无法弄清楚问题所在。

奇怪的是我什至找不到蓝牙设备，正如你在这里看到的那样，所有结果hcitool dev或rfkill不包含任何关于蓝牙设备的信息，如hci0.

我正在使用 Lubuntu 18.04 LTS，我的笔记本电脑是 Asus X555L，相关命令的结果如下：

$rfkill list

    Soft blocked: no
    Hard blocked: no

当我blueman-manager从终端运行时，我在日志中得到了这个：

SetAdapter (/usr/lib/python3/dist-packages/blueman/gui/DeviceList.py:271)
No such adapter

此外，几乎所有按钮都处于非活动状态，我无法在蓝牙管理器中执行任何操作。 蓝牙管理器中的所有按钮都处于非活动状态

我不知道问题是什么，蓝牙设备可以在我以前的 linux 操作系统上运行，也可以在我的 windows 上运行。

我已经通过 blueman(-applet) 连接了蓝牙扬声器。一切正常，但是我收到有关授权请求的永久桌面通知。

我看不到回应该请求的方法。当我关闭通知时，它会在几秒钟后重新出现，从而有效地永远遮盖了屏幕的那部分。

我怎样才能摆脱这些通知？

我无法将无线 a1016 Apple 键盘与运行 Ubuntu 17.10 的戴尔 XPS 笔记本电脑配对。

我已经看过这些线程，它们的说明对我的情况没有帮助： Pair Apple Wireless Keyboard 3rd gen with Ubuntu 16.04? 并且 Apple 无线键盘在 15.10 中无法连接

我尝试通过系统设置 GUI，其中设备被列为“未设置”。我点击它，然后有时，在我按下蓝牙键盘上的一个按钮后，我会看到 PIN 请求窗口。我输入请求的 PIN，然后 Enter，但要么什么都没有发生（通常），要么刷新窗口并请求一个新的 PIN。

我还尝试通过终端（bluetoothctl 命令提示符），尝试信任设备，然后连接/配对，但没有任何运气。错误是 ConnectionFailed 或 AuthenticationTimeout。尝试使用 blueman 包，它似乎是 bluetoothctl 的 GUI。没运气。

相同的键盘与 iMac 完美配对，因此这不是硬件问题。想法？

UPD：来自 bluetoothd 和 hcidump 的各种尝试的日志，也许这会有所帮助

尝试从 bluetoothctl 连接：
