我似乎无法升级到 TL2011：

我正在按照此页面上的说明进行操作：http://tug.org/texlive/upgrade.html 我尝试过其他镜像，但没有收到任何更新。我是不是错过了什么？

您的安装运行正常。如果更新失败，您将不会收到该no updates available消息（实际上就是它的意思），而是会收到一条错误消息，如下所示：
The supported release as specified by the repository (2011)
does not match the release version of the installation (2010), bailing out.
正如评论所说，更新只需几天时间即可出现。Karl 今晚重新启用了它们，因此如果一切正常，您应该会在几天内开始看到更新。
