yum 沒有列出儲存庫中核心的其他版本

我將我的 CentOS 更新到核心版本 4.4 (kernel-lt)，現在想kernel-devel為新核心安裝。

這個問題建議使用以下命令：

sudo yum install "kernel-devel-uname-r == $(uname -r)"

在我的情況下uname -r，評估為4.4.193-1.el7.elrepo.x86_64

$ sudo yum install "kernel-devel-uname-r == $(uname -r)"

No package kernel-devel-uname-r == 4.4.193-1.el7.elrepo.x86_64 available.
Error: Nothing to do

當我查找源目錄時，我只能看到 3.10 版本的目錄：

$ ls /usr/src/kernels/
3.10.0-1062.1.1.el7.x86_64  3.10.0-1062.1.1.el7.x86_64.debug

我試圖尋找其他版本kernel-devel的選項--showduplicates：

$ sudo yum search --showduplicates kernel-devel

如何安裝kernel-devel或kernel-headers為目前正在執行的核心（4.4）？

你說你從 kernel-lt repo 安裝了核心，所以你需要確保你啟用該 repo 來安裝任何與核心相關的東西

yum --enablerepo=elrepo-kernel install ...
