亲爱的这个出色操作系统的社区，三天来，我一直试图重新启动我用来完成所有工作的虚拟机，但一直没有成功。我迫切需要这方面的帮助。
事情是这样的：在桌面更新 GUI 报告有新更新后，我通过它安装了更新，然后重新启动了我的虚拟机。但是从那时起，它就完全卡在登录屏幕上了。我可以看到登录屏幕底部有“ubuntu”文字，但是没有登录控件（如用户选择或密码输入字段）。它完全冻结了，因为尝试按下 ctrl-shift 和任何 F 键都无法将我带到终端。然而有趣的是，如果我通过我的 vmware 工作站（版本 15.1.0 build-13591040）发送关机命令，我可以看到常规关机并停止所有服务，这对我来说似乎很奇怪。通过启动菜单启动到上一个内核会导致相同的结果。
我谷歌搜索了类似的问题，并尝试了很多推荐的方法。例如，我也从 live-cd 启动，挂载我的文件系统并检查是否有损坏的软件包。这没有帮助。我还通过 apt 和 snap 强制重新安装了几个软件包。主要是日志文件中报告错误的软件包。没有成功。最有希望的是 snap，因为它在 snap 列表中显示所有软件包都已损坏。我刷新了所有软件包（从安全启动的命令行），但结果仍然相同。
我还重新安装了 gvfs 包，因为该包与所有这些 G_UDEV_IS_DEVICE 错误消息有关。
日志文件包含多个错误，但有些错误可能在问题出现之前就已经存在了。所以我不确定哪个错误消息与这个问题有关。
非常感谢你的帮助以及你对这个出色的操作系统的贡献。 诚挚的，亨利

答案1
终于让它再次工作了！对于遇到同样问题的人，我在这里找到了解决方案： 错误 1832138
我的解决方案是启动到安全外壳（启动时按 ESC），然后从终端安装一个较新的内核：
apt install linux-generic-hwe-18.04
