如何在 Debian Wheezy 上安装 Java 1.7_51？

我正在尝试在 Debian Wheezy 上安装 Java 1.7_51：

apt-get install oracle-java7-installer=7u51-0~webupd8~1

从：http://www.webupd8.org/2012/06/how-to-install-oracle-java-7-in-debian.html

过去这是没问题的，现在我删除了旧的 1.7_45 并想要一个新的 1.7_51，但是不知何故安装失败了。

安装下载几个文件，其中之一是jdk-7u51-linux-x64.tar.gz，这是错误页面 HTML。请参阅下面的输出行：

HTTP 请求已发送，等待响应...200 OK 长度：5307 (5.2K)

[文本/html]保存至：`jdk-7u51-linux-x64。压缩文件‘

如何安装？

下面我展示的是命令输出的内容（http://pastebin.com/gPBCivvU)：

$ sudo apt-get install oracle-java7-installer=7u51-0~webupd8~1

答案1

看起来下载失败了，因为它重定向到此页面：http://download.oracle.com/errors/download-fail-1505220.html

该页面显示 Oracle 认为您未接受许可证。因此我认为他们 (Oracle) 更改了下载程序中的某些内容，现在您使用的 webupd8 安装包无法直接访问该文件。

编辑：根据下面@dmourati 的下载方法，如果您有该文件，您可以将其放在“/var/cache/oracle-jdk7-installer/”中，如果该文件在那里可用，安装程序包将跳过下载并为您完成安装。

答案2

问题是下载的包与包中的校验和不匹配：

sha256sum mismatch jdk-7u51-linux-x64.tar.gz

您应该切换到其他镜像，运行apt-get update并尝试再次安装。如果问题仍然存在，则表示有东西正在更改您下载的文件。

Debian 的软件包下载镜像/存储库已设置/etc/apt/sources.list，您可以使用任何文本编辑器编辑此文件。
