eclipse - 如何将 eclipse indigo 更新为 eclipse Luna？

在 Ubuntu 上，我正在尝试将 Eclipse Indigo 更新为 Eclipse Luna。我按照 here 给出的说明进行操作，但是当我转到“帮助 > 检查更新”时，我不确定要选择什么，不选择什么，当我选择了我认为可能正确的内容时，我收到以下错误消息:

如何更新到 Eclipse Luna？

Answer 1

只需下载新的 Eclipse Luna，删除 Indigo 并安装 Luna。不要忘记保存您的项目，以免它们被删除。检查更新将检查 Indigo 更新，而不是 Eclipse 更新。
