在 Ubuntu 16.04 上安装 docker - linux-image-extra 的问题

Question

我想在 ubuntu 16.04（在 hosteurope 的虚拟服务器上）安装 docker。

安装说明说我必须安装 linux-image-*

所以我做了：

sudo apt-get install linux-image-extra-$(uname -r) linux-image-extra-virtual

但是找不到包：

Unable to locate package linux-image-extra-4.4.0-042stab120.11

你们中有人知道如何解决这个问题吗？

TIA

apt-cache search linux-image 的输出：

Answer 1

要安装，linux-image-extra请运行以下命令：

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install linux-image-4.4.0-51-generic
sudo apt-get install linux-image-extra-4.4.0-51-generic
sudo apt-get install linux-image-extra-virtual

Answer 2

“无法找到软件包 linux-image-extra-4.4.0-042stab120.11”

您的系统运行的不是 ubuntu 内核，而是一个自定义内核，可能是为该主机本地构建的，并且其内核软件包无法从任何存储库下载，因为它们是由管理员创建并使用 dpkg 安装的（请参阅 https: //有关如何在 Ubuntu 和 Debian 中构建和安装自定义内核的详细信息，请访问/askubuntu.com/a/718662/566214 。
