Linux 马里亚德，但不干净

我使用aws的ec2创建了Amazon Linux AMI 2018.03.0（HVM），SSD卷型操作系统

然后创建下面的文件

sudo vim /etc/yum.repos.d/maria.repo

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

安装良好，运行良好

我删除了下面代码中显示的包

使用

sudo-yum-remove-y

yum-list-installed-mariadb\*

然后我切换到centos7-amd64并尝试重新安装，灾难出现了

sudo vim /etc/yum.repos.d/maria.repo

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

错误代码

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

似乎存在冲突，但未找到且未删除任何包

[ec2-user@ip-172-31-18-207 ~]$ sudo yum list installed mariadb\*
Loaded plugins: priorities, update-motd, upgrade-helper
2 packages excluded due to repository priority protections
Error: No matching Packages to list

“由于存储库优先级保护，2个包被排除”这是一个问题吗？ 如何查找和删除

我该怎么办

原因是什么

如果我的信息不够，请告诉我你缺少什么

谢谢。

您应该创建Amazon Linux 2 AMI，并重做您提到的内容
