我目前正在安装 ubuntu 服务器，并在配置阶段注意到了这一点。
这个包是起什么作用的，用于什么？
答案1
它发送有关已安装软件包的信息（但默认情况下禁用此功能，您可以使用启用它sudo dpkg-reconfigure popularity-contest）以获取软件包流行度/使用情况统计信息。

包装描述：
The popularity-contest package sets up a cron job that will periodically
anonymously submit to the Ubuntu developers statistics about the most used
Ubuntu packages on this system.
This information helps us making decisions such as which packages should go on
the first CD. It also lets us improve future versions of Ubuntu so that the
most popular packages are the ones which are installed automatically for new
users.
