我有一个旧版本的 Fedora，我想升级它。我只能使用命令行访问（通过 Windows 计算机上的 PuTTy）。从我读到的内容来看，preupgrade-cli这是我应该做的，但总是失败并显示消息“[Errno 256]没有更多的镜像可以尝试”。

Fedora 17 的更新也失败。 （我先尝试了16，因为17在列表中是乱序的，所以我从来没有注意到它。）

有什么方法可以解决这个问题并安装升级，或者我最好备份数据、擦除并从头开始？
http://mirrors.fedoraproject.org/publiclist/Fedora/17/和http://ftp.heanet.ie/mirrors/fedora-secondary/updates/17/和http://ftp.heanet.ie/mirrors/fedora-secondary/releases/17/Fedora/所有这些都表明 ftp.heanet.ie 确实托管 Fedora 17，但由于某种原因，preupgrade 命令在那里找不到它。我应该使用不同的镜像（如果是的话，如何？）或重新配置与 ftp.heanet.ie 连接中的其他内容？
答案1
从 Fedora 9 升级到任何当前受支持的 Fedora 版本可能是不可能的，因为变化太多，而且有太多损坏，不值得这样做。您最终会花费更多时间修复没人遇到过的损坏的软件包，因为这不是受支持的升级路径。从全新安装介质备份并重新安装。
答案2
我会尝试升级到 Fedora 17 - 15 可能已经足够旧，以至于镜像已将其删除，这似乎是您遇到的错误。如果这不起作用，您最好擦除并重新开始，因为与简单地恢复数据相比，您可能会花费更多的时间来让升级生效。
答案3
我最近将这款上网本从 Fedora 16 升级到 17，然后又升级到 18，但是前16 人寿终正寝。不是一步就能搞定的，查看Fedora 17的升级说明并照着做；一旦 Fedora 17 正常（请记住运行建议的清理命令！），然后转到 Fedora 18。
