安装带有卡扣和apt-get的码头

Question

我正试图在我的Ubuntu20.04上安装对接器。尝试使用apt-get和snap安装对接器：

sudo apt-get install docker

输出：

如果运行docker命令，就会得到错误：

a@ubuntu:~$ docker

Command 'docker' not found, but can be installed with:

sudo snap install docker     # version 19.03.11, or
sudo apt  install docker.io  # version 19.03.8-0ubuntu1.20.04.1

See 'snap info docker' for additional versions.

为什么系统找不到对接命令？

然后我打成平手：

sudo snap install docker 

码头命令运行良好。

为什么我可以安装插口而不能用apt-get？

Answer 1

因为那docker不是你所期望的码头工人你所期望的码头工人。docker是KDE3 3/GNOME2 2的系统托盘的包名。您可以通过访问Ubuntu包搜索或运行

apt show docker

从终端运行docker时收到的错误消息简要介绍了这种混淆。

若要安装所需的对接程序，请参阅正式文件或查看如何在Ubuntu20.04LTS上安装码头社区？
