它告诉您，系统的库不允许您安装该版本的 postgres，因为您在安装时要求提供特定版本。

如果您只想要 postgres 而不关心具体版本，请尝试：

sudo apt-get install postgres

如果您想要该特定版本并且需要它，则需要删除该libsystem0软件包以及保持其安装的任何内容。

您的系统也可能已经下载并升级了某些软件包，或者在执行软件包更新时停止了。在这种情况下，您应该运行此命令来安装任何等待处理的缺失软件包：

sudo apt-get install -f

还值得注意的是，在尝试安装新版本之前，您可能需要删除现有版本的 postgres：

sudo apt-get remove postgres*
