为什么会发生 dkms 状态“警告！构建和安装模块之间的差异”？

  • 772
generic@motorbrot:~$ sudo dkms status
zfs, 0.8.4, 5.3.0-51-generic, x86_64: installed (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING!

zfs, 0.8.4, 5.3.0-53-generic, x86_64: installed (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!)

为什么会出现此消息？

我已尝试zfs在这两个内核之一上删除并重新安装。

generic@motorbrot:~$ sudo dkms remove -m zfs -v 0.8.4 -k 5.3.0-53-generic

-------- Uninstall Beginning --------
Module:  zfs

但输出dkms status保持不变。

为什么会这样？我应该担心吗？如果我担心，我将如何解决这个问题？

drivers kernel 18.04 dkms

    您可以在输出中看到答案。

    Good news! Module version 0.8.4-1 for zavl.ko

You may override by specifying --force.

    dkms发现模块版本（不是dkms包版本）和现在运行内核中的一样，不替换。

    但是代码不同，它显示在dkms status输出中。

    您可以通过增加源代码中的模块版本或使用--force建议的选项来修复它。

    一个简短的回答是：发生这种情况是因为没有真正安装任何东西。

    看起来您需要这个具有较旧 5.0 内核的 D​​KMS 包。现在 Ubuntu 18.04 正在使用本机具有该模块的 5.3 内核。因此，您现在可以删除 dkms。
