我正在Google Cloud上试验Google Compute Engine。
我已经在Google提供的预安装的Ubuntu映像之一中设置了一个基本的LAMP环境，在这种情况下，Ubuntu 14.04 LTS（amd64可信映像构建于2016-01-14）。
我安装的软件与我已经在Digital Ocean的许多其他服务器中安装的完全相同，并且还有我家中的Virtual Box。
我选择的机器是 1 vCPU（f1-micro），只有 0,6 GB 的 RAM，这对于他们管理的轻松工作来说很好。
使用 apt-get update 和 apt-get 升级升级系统后，系统崩溃了，再也没有启动过。我已经多次停止并重新启动实例，但它已经死了，在尝试重新启动时，其 CPU 使用率为 400%。
升级意图后我遇到的错误是：

有人有类似的问题吗？我应该责怪什么？RAM 的数量、原始图像、处理器太小、谷歌机器？
我喜欢我所看到的谷歌云机器，但我不能把这两个步骤都放进去，因为我不确定它们是否可以随时以这种方式崩溃。 在这种体验之前，所有虚拟机都像坚硬的岩石一样，即使在激烈的安装和卸载任何类型的软软件之后，也从未崩溃。这个坠毁了，里面几乎没有任何东西。
提前感谢您的意见。
新细节：我已经从崩溃前的图像中恢复了机器。现在我可以升级系统，但升级后仍然存在错误。我不知道我现在是否可以信任这个系统的完整性：
12 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

自动更新在"无人值守升级"中配置。
禁用;
注释掉/etc/apt/apt.conf.d/50unattended-upgrades文件的Allowed-Origins
和/或添加：
"APT :: Periodic :: Unattended-Upgrade" 0 lines ";"
在/etc/apt/apt.conf.d/10periodic文件中
如果update-initramfs内存不足（我在具有 600 MB 内存的谷歌云实例上遇到了这个问题），请尝试：
export XZ_DEFAULTS="--memlimit=80MiB"
然后重试apt-get upgrade（或dpkg --configure -a）。
您可能希望在/etc/bash.bashrc中添加它，以便在运行时使用它unattended-upgrades。
