我有两台 ubuntu 服务器（20.04.5）。一个的内核版本为 5.4.0-137-generic，另一个的内核版本为 5.15.0-66-generic。我想让它们具有相同的内核版本（5.15.0-66-generic）。但是当我运行sudo apt-get install linux-image-5.15.0-66-generic命令时，出现以下错误消息。
Building dependency tree

E: Unable to locate package linux-image-5.15.0-66-generic
E: Couldn't find any package by glob 'linux-image-5.15.0-66-generic'
E: Couldn't find any package by regex 'linux-image-5.15.0-66-generic'
当我检查列表中的可用内核版本时，列表中没有我要查找的内核版本。

我想知道为什么会发生这种情况以及解决这种情况的方法。
答案1
linux-image-5.15.0-66-generic是 Jammy 的拟议更新（22.04，而不是 20.04），但它没有升级到更新存储库；它已被替换为linux-image-5.15.0-67-generic。
如果两台服务器都运行 20.04，您应该坚持使用 5.4 内核20.04 支持。最新发布的 5.4 内核软件包是 5.4.0-139，建议更新中包括 5.4.0-144。
