是的，我知道Debian Wheeze已经过时了。
但是可以通过“ apt-get”安装PHP扩展吗？
也许我需要为过期的LTS使用其他来源列表吗？

请注意，Debian 7 (wheezy) is an obsolete stable release（强调过时）。
我建议您不要继续使用它。
您得到的错误仅仅是由于发布已过时且存储库不再有效的结果。
社区已做出一些努力来提供Long Term Support和Extended Long Term Support，但是最好确保您的用例确实需要它。
Frexian协调社区为旧版本提供支持的工作。
您可以更新源列表以尝试获取LTS软件包，但这将要求您确切地确认所需的软件包以及软件包是否一直处于更新状态。
您是否有足够的理由不升级到最新版本？
