我知道类似的问题已经被问过无数次了，但到目前为止我还没有找到适合我的情况的答案。
我在 OpenVZ 容器内运行 32 位 14.04 服务器，它提供以下内核：
$ uname -r
2.6.32-042stab116.2
不确定它是如何/为何开始的，但apt一直尝试（并失败）升级到 3.13 系列，最终结果是这样的：

我的理解是，内核完全由 OpenVZ 主机负责，并且有人建议我干脆把这些图片全部删掉，系统无论如何都会忽略这些软件包。但是，我尝试完全删除这些软件包的所有尝试都失败了，并出现了各种错误消息。
当我尝试明确清除所有不需要的 Linux* 软件包时，发生了以下情况。
使用 aptitude 代替 apt-get删除了一些软件包并将所有剩余图像的状态更改为pH，但并未解决问题：

我再次对上面的 3.13 软件包列表运行 aptitude，这次所有标题都消失了，但是“额外”的图像仍然存在。
$ dpkg -l |grep linux

我给了再试一次，这是输出。看起来，为了清除这些额外的图像（具有明显未满足的依赖关系，因为相应的图像已经消失），aptitude缺少所需的一些文件：
depmod: FATAL: could not load /boot/System.map-3.13.0-100-generic: No such file or directory
