那应该是只能重装？等于 iPhone 的 DFU 模式或者高通的 9008 模式强刷 。
这种 OTA 更新没有回滚功能的话如果中途终端崩溃了，或者中途突发断电了，都会无法开机的。

最保险的方法还是重装最新版本的镜像文件。
小众的系统别用 OTA 。

@Fo3256Go 答非所问，统信系统是 PC 上的 Linux 发行版（不懂的话理解成一个类似 Fedora 或者 Ubuntu 的系统就可以），哪来的“强刷”“OTA”的说法？而且 OP 的问题描述里也不涉及中途断电崩溃的问题。

UOS 服务器系统的免费版不是社区版，应该也是要激活免费授权之后才能在线更新的，可以到系统设置里面看看有没有激活。

我也遇到了类似的问题,yum 源无法使用,链接访问 401
