每日消息仍显示有更新可用

我已以 root 身份登录并运行

apt-get update
apt-get upgrade

之后重新启动了。

但是，当天的消息仍然显示我有 7 个包可以更新。

已尝试运行update-motd但仍然显示相同的内容。

我如何查看和更新​​这些包？

输出apt list --upgradable：

linux-generic/xenial-updates,xenial-security 4.4.0.75.81 i386 [upgradable from: 4.4.0.59.62]
linux-headers-generic/xenial-updates,xenial-security 4.4.0.75.81 i386 [upgradable from: 4.4.0.59.62]
linux-image-generic/xenial-updates,xenial-security 4.4.0.75.81 i386 [upgradable from: 4.4.0.59.62]
N: Ignoring file '50unattended-upgrades.ucf-old' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension

输出/usr/lib/update-notifier/apt-check --human-readable：

7 packages can be updated.
7 updates are security updates.

我可以通过手动升级 linux-headers-generic 包来解决这个问题：

sudo apt-get install linux-headers-generic
