scala - 无法在线安装 sbt（按照官方指南）

问题描述

在 Ubuntu16.04 上，来自这个官方页面： https ://www.scala-sbt.org/download.html

echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudo apt-get update
sudo apt-get install sbt

我得到了什么：

fino@envy:bin$ echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
[sudo] password for fino: 
deb https://dl.bintray.com/sbt/debian /

fino@envy:bin$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823

我尝试直接连接到互联网或“export all_proxy=sock5h://ip:port”，因为我在大陆:-)

您无法连接以keyserver.ubuntu.com验证公钥，所以我认为这不是 sbt 或其分发的问题。我建议你手动下载 deb 文件，或者找出一些其他可用的密钥服务器。
