Bluez 守护进程未运行

抱歉再次问这个问题，我已经浏览了所有类似的帖子并尝试了一些建议，但没有任何成功。

当我尝试连接到蓝牙管理器时，我得到了这个结果。

在此处输入图片描述

详情如下。

答案1

尝试这个：

sudo systemctl enable bluetooth.service

还要确保您的发行版安装了蓝牙包...（仅供参考，请在 arch linux 论坛中搜索）

答案2

请参阅此链接了解一些选项： https://forums.debian.net/viewtopic.php?t=144923
在我的例子中（Ubuntu 18.04.6 LTS），有效的方法是：sudo systemctl restart bluetooth，然后启用它
