我无法在我的ubuntu 18.10宇宙系统上安装erlang/Elixir

Question

我正在为unix类系统https://elixir-lang.org/install.html#unix-and-unix-like执行上的步骤。

这就是我得到的错误

sudo apt-get install esl-erlang
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 esl-erlang : Depends: libncurses5 but it is not installable
              Depends: libsctp1 but it is not installable
              Recommends: erlang-mode but it is not going to be installed
E: Unable to correct problems, you have held broken packages

我也尝试过使用asdf-vm，但仍然存在相同的libcurses5问题

问题是，在cosmic上，存储库在http://archive.ubuntu.com上不可用。

在/etc/apt/Sourcees.list中更改它们，也就是用http://old-releases.ubuntu.com替换所有出现的http://archive.ubuntu.com就行了。
