我刚刚使用终端将我的电脑从 Ubuntu 18.04 升级到 Ubuntu 20.04。一切顺利(除了主板上嵌入的视频卡的一些问题,但我已经预料到了这一点,我应该已经修复了它),但现在我无法打开蓝牙开关。我有一个蓝牙适配器(根据 lsusb,是 Qualcomm Atheros Communications AR3011 Bluetooth),但我没有设法打开它。如果我运行,sudo modprobe btusb
我会收到一条错误消息,提示:
modprobe: FATAL: Module btusb not found in directory /lib/modules/5.4.0-1053-gke
我已经升级(使用update
和dist-update
),但所有包都是最新的。
