标签： update

今天下载了华为的openEuler。装在电脑虚拟机里。

yum update 发现没有配置repo，于是想把Repo源换成华为的，按照 华为云操作 https://mirrors.huaweicloud.com/

在/etc/yum.repos.d目录下，创建文件EulerOS.repo，设置为

[base]
name=EulerOS-2.0SP5 base
baseurl=http://mirrors.huaweicloud.com/euler/2.5/os/x86_64/
enabled=1
gpgcheck=1
gpgkey=http://mirrors.huaweicloud.com/euler/2.5/os/RPM-GPG-KEY-EulerOS

然后update。显示出错：

[root@Euler ~]# yum update

如上面所示，update 总是出错。

然后换成 EulerOS-2.0SP3 base ，SP2，SP1 都是依然出错。

最后在 文档的 “系统安装”中找到一个 repo源 的链接：https://openeuler.org/zh/docs/20.03_LTS/docs/Releasenotes/%E7%B3%BB%E7%BB%9F%E5%AE%89%E8%A3%85.html

正确的repo源地址是：http://repo.openeuler.org/openEuler-20.03-LTS/OS/x86_64/

/etc/yum.repos.d/EulerOS.repo 配置为：

[base]
name=openEuler-20.03-LTS base
baseurl=https://repo.openeuler.org/openEuler-20.03-LTS/OS/x86_64/
enabled=1
gpgcheck=1
gpgkey=https://repo.openeuler.org/openEuler-20.03-LTS/OS/x86_64/RPM-GPG-KEY-openEuler

之后再次update成功！

yum clean all
yum makecache
yum update

openEuler-20.03-LTS base                                                                                                                                                            36 kB/s | 2.7 MB     01:18

Dependencies resolved.
Nothing to do.
Complete!

原因在于： openEuler 与 华为云中的 EulerOS 是两个不同的发行版本!!!
