[官方文档](https://support.huaweicloud.com/csg_faq/csg_04_1209.html)

1. 备份本地Yum源

   ```bash
   mkdir -p /etc/yum.repos.d/backup/
   mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup/
   ```

2. 编辑华为源文件

   ```bash
   vi /etc/yum.repos.d/EulerOS.repo
   ```

   内容如下

   ```bash
   [base]
   name=EulerOS-2.0SP8 base
   baseurl=http://repo.huaweicloud.com/euler/2.8/os/aarch64/
   enabled=1
   gpgcheck=1
   gpgkey=http://repo.huaweicloud.com/euler/2.8/os/RPM-GPG-KEY-EulerOS
   ```

3. 删除缓存数据

   ```bash
   yum clean all
   ```

4. 创建元数据缓存

   ```bash
   yum makecache
   ```
