APT 有时会让我感到震惊。两周前我进行了跟踪apt update，apt upgrade并被推荐使用 3.13 内核，尽管我使用的是 4.4 内核。我忽略了这一点。一周后我重新运行更新和升级，没有升级建议。今天，3.13 建议又回来了。这是怎么回事？我该如何防止这些复古内核被推荐？

您使用的是 HWE 内核版本，但仍有一个指向 3.13 内核的元包。Ubuntu 14.04 最初发布时使用的是 3.13 内核。
现在您可以获得 3.13 和 4.4 内核的更新。
如果你不想获取 3.13 更新，请运行以下命令删除元包
sudo apt-get remove linux-image-generic linux-headers-generic linux-tools-generic
linux-image-generic-lts-xenial您将通过元包获得 4.4 内核的更新linux-headers-generic-lts-xenial。
如果愿意，您还可以删除所有 3.13 图像、标题和工具包。
