今天早上更新了 20.04,现在触摸板冻结了,我无法连接到互联网。
nmcli d 给出:
DEVICE TYPE STATE CONNECTION
virbr0 bridge disconnected --
lo loopback unmanaged --
vurbr0-nic tun unmanaged --
我希望如果我可以连接到互联网,我可以尝试再次更新,以解决触摸板问题,但不确定如何开始尝试解决这个问题,甚至不确定哪些信息对于获得一些建议有用。
任何帮助都非常感谢。
编辑内容如下:
硬件:联想 Legion 5
Ubuntu:20.04 桌面版
我无法看到 sudo lshw -C network 的所有结果,因为终端窗口太小,而且我无法调整大小,因为触摸板已冻结。但我可以看到:

cat /etc/network/interfaces 显示“没有这样的文件或目录”
cat /etc/netplan/*.yaml 给出:

答案1
笔记:您需要弄清楚如何在测试期间禁用您的 VPN。
您的 /etc/netplan/*.yaml 文件不正确。将其更改为如下所示...保持缩进和间距相同...
改变:
#Let NetworkManager manage all devices on this system
network:
version: 2
renderer: Network Manager
更改为:
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
sudo netplan generate
sudo netplan apply
reboot

是时候备份重要文件并重新安装 Ubuntu 了。
