我最近遇到了 Xubuntu 18.04 无法始终唤醒的问题。似乎只在早上出现。我提取了系统日志，看到一些故障，例如“无法启动 snap.canonical-livepatch”。可能是这个原因吗？有没有关于如何解决此唤醒问题的建议？我没有找到附加文件的方法，因此将系统日志的一部分粘贴到下面，但行格式丢失了。在 6:29 进行了硬重启以恢复。

答案1
我不确定这是否会对任何人有帮助，但还是要说一下。最终我的系统无法启动。启动前可用的恢复功能也不起作用。我有一张 Lubuntu 18.04 LTS i386/ 的 CD，在启动时加载它时，它提供了几种恢复方法，这些方法也不起作用，但其中一种方法确实显示需要在 /dev/sda1 上进行 fsck。然后我加载了一个实时版本的 ubuntu 并运行 sudo umount /dev/sda1，然后运行 sudo fsck /dev/sda1。这发现了几个错误并能够纠正。我重新启动后系统又可以正常工作了。
