我怎样才能解决这个问题？

Answer 1

有几个问题在起作用：

1)

Err:4 http://dl.ajaxplorer.info/repos/apt squeeze InRelease
  The following signatures were invalid: KEYEXPIRED 1530185191

有关这一点，请参见例如更新存储库时GPG KEYEXPIRED错误

如果无法使用apt-key获取此存储库的当前公钥，则需要查看安装程序期望密钥位于何处。目前正在逐步取消使用apt-key，以便在文件系统中存储各个密钥。

查找deb条目，该条目对应于/etc/apt中的某个存储库。如果这个deb条目中包含类似于[signed-by=/usr/share/keyrings/-archive-keyring.gpg]的内容，则需要用当前键刷新其中提到的文件。在存储库的描述中，可能有关于如何下载密钥的说明。

2)

也没有名为update (或updata)的包，所以您无法安装它。这是您的系统在E: Unable to locate package updata中告诉您的。您可能希望再次了解apt的系统功能，所以您不会再去看一些毫无意义(无意冒犯)的东西，比如sudo apt-get install updata。

3)

您似乎已经配置了一些存储库，这些存储库提供了一些您需要的包，但并不是所有的包。例如，当您尝试安装cpp-6时，它还需要gcc-6-base。对于可用的cpp-6版本，您需要gcc-6-base 6.2.0-3ubuntu11~12.04，但您只有gcc-6-base 6.0.1-0ubuntu1。

4)

正如guiverc在他对您的问题的评论中所提到的，您似乎至少使用了一些相当老的软件。如您所见，您想要安装的gcc-6-base包(如果您有它的话)是用于Ubuntu12.04的，所以从2012年开始。

总的来说，您可能需要对您的机器做一次不太好的弹簧清洗。如果可以的话，可能会让某人亲自查看，如果可以的话，也可以从本地Linux用户组中查看。最终，备份您想要保存的所有数据并执行新的安装可能更容易。但远距离的决定并不容易。
