如何在 Debian/Ubuntu 上手动安装安全更新?

在 Linux 上通过命令行安装一个包程序是一件简单的事。在一行命令中组合使用多个命令能让你更加简单地完成任务。

安全更新也同样如此。

在这个教程里面,我们会向你展示如何查看可用的安全更新,以及如何在 Ubuntu、LinuxMint 等等这些基于 Debian 的系统中安装它们。

有三种方法可以完成这件事,下面会详细地描述这三种方法。

作为一个 Linux 管理员,你应该让你的系统保持为最新,这会让你的系统更安全,保护你的系统抵抗意想不到的攻击。

如果你因为一些应用的依赖问题不能解决,导致不能给所有的系统进行全部更新。那至少,你应该打上安全补丁来让你的系统 100% 符合要求。

方法一:如何检查 Debian/Ubuntu 中是否有任何可用的安全更新?

在进行补丁安装之前,检查可用安全更新列表始终是一个好习惯。它会为你提供将在你的系统中进行更新的软件包的列表。

默认情况下,你的系统上应该是已经安装了 unattended-upgrades 包的。但是如果你的系统没有装这个包,那么请使用下面的命令来安装它。

使用 APT-GET 命令  或者 APT 命令  来安装 unattended-upgrades 包。

  1. $ sudo apt-get install unattended-upgrades
  2. $ sudo apt install unattended-upgrades

什么是试运行? 大多数的 Linux 命令都有一个试运行选项,它会给出实际的输出但不会下载或安装任何东西。

为此,你需要在 unattended-upgrades 命令中添加 --dry-run 选项。

  1. $ sudo unattended-upgrade --dry-run -d
  2. Initial blacklisted packages:
  3. Initial whitelisted packages:
  4. Starting unattended upgrades script
  5. Allowed origins are: o=Ubuntu,a=bionic, o=Ubuntu,a=bionic-security, o=UbuntuESM,a=bionic
  6. Using (^linux-image-[0-9]+\.[0-9\.]+-.*|^linux-headers-[0-9]+\.[0-9\.]+-.*|^linux-image-extra-[0-9]+\.[0-9\.]+-.*|^linux-modules-[0-9]+\.[0-9\.]+-.*|^linux-modules-extra-[0-9]+\.[0-9\.]+-.*|^linux-signed-image-[0-9]+\.[0-9\.]+-.*|^kfreebsd-image-[0-9]+\.[0-9\.]+-.*|^kfreebsd-headers-[0-9]+\.[0-9\.]+-.*|^gnumach-image-[0-9]+\.[0-9\.]+-.*|^.*-modules-[0-9]+\.[0-9\.]+-.*|^.*-kernel-[0-9]+\.[0-9\.]+-.*|^linux-backports-modules-.*-[0-9]+\.[0-9\.]+-.*|^linux-modules-.*-[0-9]+\.[0-9\.]+-.*|^linux-tools-[0-9]+\.[0-9\.]+-.*|^linux-cloud-tools-[0-9]+\.[0-9\.]+-.*) regexp to find kernel packages
  7. Using (^linux-image-4\.15\.0\-51\-generic$|^linux-headers-4\.15\.0\-51\-generic$|^linux-image-extra-4\.15\.0\-51\-generic$|^linux-modules-4\.15\.0\-51\-generic$|^linux-modules-extra-4\.15\.0\-51\-generic$|^linux-signed-image-4\.15\.0\-51\-generic$|^kfreebsd-image-4\.15\.0\-51\-generic$|^kfreebsd-headers-4\.15\.0\-51\-generic$|^gnumach-image-4\.15\.0\-51\-generic$|^.*-modules-4\.15\.0\-51\-generic$|^.*-kernel-4\.15\.0\-51\-generic$|^linux-backports-modules-.*-4\.15\.0\-51\-generic$|^linux-modules-.*-4\.15\.0\-51\-generic$|^linux-tools-4\.15\.0\-51\-generic$|^linux-cloud-tools-4\.15\.0\-51\-generic$) regexp to find running kernel packages

如果在终端里,上面的命令输出说 “No packages found that can be upgraded unattended and no pending auto-removals”,这意味着你的系统已经是最新的了。

如何在 Debian/Ubuntu 中安装可用的安全更新?

如果你在上面的命令输出中获得了任意的软件包更新,就运行下面的命令来安装它们。

  1. $ sudo unattended-upgrade -d

除此之外,你也可以使用 apt-get 命令来进行安装。但是这个方法有点棘手,我会建议用户用第一个选项。

方法二:如何使用 apt-get 命令在 Debian/Ubuntu 中检查是否有可用的安全更新?

在你的 Debian/Ubuntu 系统中运行下面的命令来查看可用安全更新的列表。

如何在 Debian/Ubuntu 系统中使用 apt 命令来安装可用的安全更新?

如果你在上面命令的输出中发现任何的软件包更新。就运行下面的命令来安装它们。

  1. $ sudo apt list --upgradable | grep -e "-security" | awk -F "/" '{print $1}' | xargs apt install

同样,下面的文件也会告诉你更新包的总数。

  1. $ sudo cat /var/lib/update-notifier/updates-available
  2. 190 packages can be updated.
  3. 39 updates are security updates.
