我想在 ubuntu 16.04 上安装 docker（在 hosteurope 的虚拟服务器上）。
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
但是没有找到该包：
Unable to locate package linux-image-extra-4.4.0-042stab120.11
你们中有谁知道如何解决这个问题？

答案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
答案2
这是我的方法安装 docker-engine，看看是否有帮助
我按照码头工人官方页面安装docker-engine，但我遇到了和你一样的问题
因此，忽略安装 linux-image-extra-* 软件包，并继续安装 docker-engine
$apt-get install docker-engine

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
docker-engine : Depends: init-system-helpers (>= 1.18~) but 1.14 is to be installed
Depends: lsb-base (>= 4.1+Debian11ubuntu7) but 4.1+Debian11ubuntu6 is to be installed
Depends: libdevmapper1.02.1 (>= 2:1.02.97) but 2:1.02.77-6ubuntu2 is to be installed
Depends: libltdl7 (>= 2.4.6) but it is not going to be installed
Depends: libsystemd0 but it is not installable
Recommends: aufs-tools but it is not going to be installed
Recommends: cgroupfs-mount but it is not installable or
cgroup-lite but it is not going to be installed
运行以下命令查看每个可供安装的 Docker 版本返回的条目。
~# apt-cache policy docker-engine
docker-engine:
Installed: (none)
Candidate: 1.12.5-0~ubuntu-xenial
Version table:
1.12.5-0~ubuntu-xenial 0
500 https://apt.dockerproject.org/repo/ ubuntu-xenial/main amd64 Packages

1.12.4-0~ubuntu-xenial 0
500 https://apt.dockerproject.org/repo/ ubuntu-xenial/main amd64 Packages
运行以下命令来安装特定版本的 docker-engine（从上面：候选版本：1.12.5-0~ubuntu-xenial）
apt-get install docker-engine=1.12.5-0~ubuntu-xenial
docker 安装成功！
答案3
您可能需要安装一些 Linux 映像附加组件。运行以下命令，然后重试：
sudo apt install linux-image-extra-virtual
答案4
“无法找到软件包 linux-image-extra-4.4.0-042stab120.11”
你的系统运行的不是 ubuntu 内核，而是一个为该主机本地构建的自定义内核，并且它的内核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://askubuntu.com/a/718662/566214有关如何在 Ubuntu 和 Debian 中构建和安装自定义内核的详细信息)。
