如何在CentOS上安装docker?

遇到一些麻烦安装泊坞窗:

[root@rolly ~]# 
[root@rolly ~]# sudo yum install -y yum-utils
Docker CE Stable - x86_64                                                                            42 kB/s | 3.5 kB     00:00    
Package yum-utils-4.0.12-3.el8.noarch is already installed.
Dependencies resolved.
Nothing to do.

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
[root@rolly ~]# 
[root@rolly ~]# lsb_release -a

[root@rolly ~]# 

也许我应该一起去nobest吗?

答案1

如果最新版本无法安装,您可以运行:

dnf install docker-ce --nobest

安装不是最后一个版本的另一个版本。有点悲伤,但它有效。
