我的系统出现了某种问题（它是一个具有 2 GB RAM 和 50 GB 硬盘的 kvm vm）。当我尝试使用 apt-get 安装“linux-image-3.2.0-38-generic-pae”时，系统提示我设备上没有剩余空间：

现在 - 磁盘空间不应该是一个问题：
# df -h

因此 - /tmp 安装在具有 29 GB 可用磁盘空间的分区上，有 2 GB 的 RAM，其中根据“顶部”大部分是未使用的，有一个 4 GB 的交换分区...我没有看到问题 :(
如何让这个东西运行起来？

这里似乎有一个与您的问题非常相似的描述：

看起来重启可能是个办法。但是，在重启之前，您应该确保根级内核符号链接和 /boot 的内容都正确无误，否则您可能无法启动。
