manjaro 的最后一次更新，由于某种原因不再允许我启用 blueman。这是错误：

Exception occurred org.bluez.Error.Blocked: Blocked through rfkill
已安装 gnome-themes-standard。
他们在 github 上将我的票证标记为 bug，我想我永远不会收到答案，必须等到 blueman 的下一个版本才能修复它。我等不及那么久了，还有其他可用于 xfce 的蓝牙小程序吗？
答案1
Lynob 答案的小更新：我遇到了同样的问题，并发现blueman-applet至少在 v.1.99 中具有相同的错误，但有问题的代码位于/usr/lib/python2.7/dist-packages/blueman/main/KillSwitchNG.py.
第 87-88 行：
标志 |= os.O_NONBLOCK
self.fd = os.open("/dev/rfkill", flags)
...
要解决该问题，还必须在调用之前添加以下行来binary mode设置：flagsopen(...)
标志 |= os.O_BINARY
答案2
我跑了
sudo rfkill unblock bluetooth
它似乎有效，但是在 github 上，Christopher Schramm 重新打开了我的票证，并且仍然标记为错误，也许他正在调查一个我不知道的错误，也许是 GTK 错误。对我来说，我只关心它是否有效。
编辑
Christopher 发现了一个实际的错误，请根据此查看blueman/plugins/mechanism/RfKill.py并更改您的文件，或者等待更新推送。第 15 行应该是这样的
f = open('/dev/rfkill', 'wb')只需添加 b
