我的内核何时更新和安装

  • 772

这个问题与更新内核时避免丢失内核 linux-modules-extra-XX-generic有关

更新内核的过程需要几个步骤。我的问题是：

  1. 在更新内核的所有可能方法中（例如，https://ostechnix.com/different-ways-to-update-linux-kernel-for-ubuntu/可能还有其他未列出的方法），我怎么知道哪个被用于我的系统？我实际上的意思是确认它是否来自自动更新（unattended-upgrades，或者其他？）
  2. 我如何知道导致新内核成为当前的每个步骤何时发生（安装内核包、重新启动等）？我的意思是做一些“取证”。
updates upgrade log kernel apt

    我列出了我可以收集的信息，以及如何收集。下面，详细介绍。

    1. 每个软件包的安装方式（哪种方法，自动/手动）。
      与apt list --installed | egrep '^linux' | grep $(uname -r).
    2. 每个软件包的安装时间和方式。 打开（我复制并
      在其他地方复制以保持清洁）。grep $(uname -r)/var/log/apt/history.log*sudo gunzip
    3. 安装每个软件包时。
      随着grep $(uname -r)开/var/log/dpkg.log*。
    4. 当电脑重新启动时。我不知道此信息是否完整（例如，涵盖因停电而导致的关机 等）
      。这给出了重新启动的日期/时间，以及我不知道它们的含义的数字 [0.18????]。 随着开。这只是最后一次重新启动（每个文件一个，所以我猜每个文件都在重新启动时开始），只有数字 [0.18????]。 随着开。与日期/时间 相比，这提供了更少的重新启动。on没有提供更多信息。grep reboot/var/log/kern.log*
      grep reboot/var/log/dmesg*kern.log*
      grep reboot/var/log/syslog*dmesg*
      grep shutdown/var/log/syslog*

    每个软件包的安装方式（哪种方法，自动/手动）

    从apt list --installed | egrep '^linux' | grep $(uname -r)我得到4个包裹：

    linux-image-5.4.0-42-generic/focal-updates,focal-security,now 5.4.0-42.46 amd64 [installed,automatic]
linux-modules-5.4.0-42-generic/focal-updates,focal-security,now 5.4.0-42.46 amd64 [installed]
linux-modules-extra-5.4.0-42-generic/focal-updates,focal-security,now 5.4.0-42.46 amd64 [installed]
linux-modules-nvidia-390-5.4.0-42-generic/focal-updates,focal-security,now 5.4.0-42.46 amd64 [installed,automatic]

    这表明内核已自动更新。
