我刚刚安装了ubuntu服务器64位到我的raspberry pi (与官方的映像程序)，开始使用它，但许多软件包找不到。比如ruby，python3-libotrrent等，我得到的不是E: Unable to locate package libboost-python就是E: Package 'python3-libtorrent' has no installation candidate。您有什么解决方案吗，我以前使用过raspbian，它工作得很好，但是速度更慢。谢谢你的回复！

我看过这两本指南了。一个用于Ubuntu，另一个用于拉斯班 (都是基于Debian的，因此大多数包是相同的，可以从公共来源安装)。

两者似乎都使用sudo apt install ruby-full，鲁比满，而不是红宝石。

如果这不起作用，你可以考虑使用sudo snap install ruby –classic，如果你可以使用snap。

在我的盒子上运行apt列表：

apt list ruby
Listing... Done
ruby/bionic 1:2.5.1 amd64

此外，您应该用版本更新您的问题。
