安装以太坊时出错：包“ethereum”没有安装候选

Question

我按照本文中的步骤在 Ubuntu 17.10 上安装以太坊：https ://medium.com/@mvmurthy/full-stack-hello-world-voting-ethereum-dapp-tutorial-part-2-30b3d335aa1f

但是当执行以下命令时：

sudo apt-get install ethereum

我得到以下信息：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package ethereum is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'ethereum' has no installation candidate

Answer 1

您添加了以太坊存储库吗？如果没有，请尝试以下操作：

sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum

Answer 2

似乎与以太坊和 Ubuntu 17.10 的最新稳定版本存在兼容性问题；并且可以毫无问题地安装最新的不稳定版本：

sudo apt-get install ethereum-unstable

然而，这意味着在以太坊的下一个稳定版本中不会有任何问题。
