apt-get-update和apt-get-upgrade都不需要更新或安装。我可以安装任何其他软件包。
如果有人愿意帮助我，谢谢：-）
从您收到的错误来看，您没有与当前PHP包匹配的可用包。你有两个选择。首先，你可以使用新的PHP版本（不需要编译代码。）如果你已经为你的项目安装了composer，你可以很容易地做到这一点：
php composer.phar require geoip2/geoip2:~2.0
或者，第二种选择是安装PECL的原始软件包。假设您已经安装了适当的PEAR包，并且有可用的开发工具（例如make和gcc），您可以尝试以下步骤：
apt-get install libgeoip-dev
pecl install geoip
