我在我的服务器设备上运行了软件更新程序,现在网络无法正常工作,即使是本地网络也不行。没有 wifi,也没有以太网。
我运行了这个:
$ cat /etc/netplan/01-network-manager-all.yaml
并得到这个:
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
有没有办法查看我最近安装了哪些更新,以了解这个问题可能源自何处?或者有办法彻底解决这个问题?
编辑1:运行:
sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status
并收到:
dpkg-query: package 'linux-modules-extra-5.15.0-70-generic' is not installed and no information is available
编辑 2:运行:ip a
并收到:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
还跑了iwconfig
并收到了lo no wireless extensions.
编辑 3:我也执行了以下帖子中的步骤。但没有用。 Ubuntu 无法检测 wifi 或以太网。*-Windows/Ubuntu 双启动中网络未声明
编辑4:sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status
返回Status: install ok installed
并sudo lshw -C network
显示我的网络适配器无人认领。

编辑 5:输入sudo modprobe ath9k
并得到modprobe: ERROR: could not insert 'ath9k': Operation not permitted
然后输入ps aux | grep Network
,得到:
