昨天我在 Lubuntu 14.04 更新机器时遇到了问题,我不得不按照这个勾选的答案进行操作 升级时可用磁盘空间不足
这个答案很有效,但今天当我打开电脑时,我无法连接到任何网络(无论是 wifi 还是以太网),它们就是不显示。此外,运行:sudo lshw -C network -numeric 我得到

如您所见,两个网络都显示为无人认领,根据我所读的内容,我怀疑这是驱动程序问题。有没有办法让它重新工作,而不必重新安装。我只是不想从头开始设置我的所有开发环境。

答案1
我建议您通过选择 GRUB 菜单中的较早版本的 Linux 映像(如我上面所链接的)重新启动它。然后,重新安装有故障的版本:
sudo apt-get install --reinstall linux-image-3.13.0-45-generic
完成后,重新启动并测试。
