升级Ubuntu 23.04后蓝牙管理器无法连接设备的问题求助

大家好，我最近把系统从Ubuntu 22.10升级到23.04后，蓝牙彻底没法正常工作了，遇到了几个棘手的问题：

• 尝试冷连接我的便携音箱时，设备刚连上一秒就立刻断开
• 就算完成配对并把设备标记为「信任」，它也不会自动连接，每次手动连接都会弹出错误：Connection Failed: br-connection-profile-unavailable

我查看了蓝牙服务的运行状态，输出内容如下：

root@:/home/# service bluetooth status

我已经试过这些解决办法，但都没有效果：

• 多次重启系统
• 修改/etc/bluetooth/main.cnf的多种配置参数
• 重新安装Ubuntu系统

我猜想这可能是Ubuntu 23.04早期版本的已知bug，但还是想问问有没有人遇到过类似问题，或者有什么可行的解决思路？
