我该如何解决这个问题？

答案1

有几个问题正在发生：

1）

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

例如，参见更新存储库时出现 GPG KEYEXPIRED 错误

如果您无法使用 获取此存储库的当前公钥apt-key，则需要查看您的设置期望密钥位于何处。使用apt-key当前已逐步淘汰，取而代之的是将单个密钥存储在文件系统中。

在 中的某个位置查找deb与此存储库相对应的条目/etc/apt。如果此条deb目中有类似内容[signed-by=/usr/share/keyrings/<myrepository>-archive-keyring.gpg]，则需要使用当前密钥刷新其中提到的文件。存储库描述中可能有关于如何下载密钥的说明。

2）

是update，不是updata;) 此外，没有名为update（或updata）的软件包，因此您无法安装它。这是您的系统在 中告诉您的E: Unable to locate package updata。您可能想再次查看 的系统apt，这样您就不会遇到基本上毫无意义（无意冒犯）的事情，例如sudo apt-get install updataagain。

3）

您似乎配置了一些提供一些您需要但不需要的软件包全部其中。例如，当您尝试安装时cpp-6，它还需要。对于您gcc-6-base的版本cpp-6做有可用，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 在对你的问题的评论中提到的那样，你似乎至少使用了一些相当老旧的软件。如您所见，gcc-6-base您要安装的软件包（如果有的话）适用于 Ubuntu 12.04，因此是 2012 年的。

总的来说，您可能需要对您的机器进行一次彻底的春季大扫除。也许请人亲自检查一下会有所帮助，如果可以的话，也许可以请您当地的 Linux 用户组的人来检查。最终，备份所有要保留的数据并进行全新安装甚至可能更容易。但这并不容易远程决定。
