Indy-node安装在Ubuntu上失败

Question

我正在尝试在新的Ubuntu 18.04计算机上安装indy-node，以创建一个具有4个节点的小型网络。

[跟随installation instructions时出现以下错误：

localhost:~$ sudo apt-get install indy-node

The following packages have unmet dependencies:
 indy-node : Depends: indy-plenum (= 1.12.2) but it is not going to be installed
             Depends: libsodium18 but it is not installable
E: Unable to correct problems, you have held broken packages.

我尝试安装libsodium18，但出现以下错误：

Package libsodium18 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 'libsodium18' has no installation candidate

同样，尝试安装indy-plenum时会遇到很多“未满足的依赖关系”错误。

**注意：*这一切都发生在以下回购中：

sudo bash -c 'echo "deb https://repo.sovrin.org/deb xenial stable" >> /etc/apt/sources.list'

当我尝试为仿生而不是氙气添加软件包时，出现以下错误：

repository 'https://repo.sovrin.org/deb bionic InRelease' doesn't have the component 'stable'

我也曾尝试通过python + pip安装indy-node，但这似乎也不起作用。

有人成功安装了indy-node，如果可以，您可以共享秘密吗？

Answer 1

最终解决方案是降级到Ubuntu 16.04

Answer 2

我们已经使用Ubuntu 18.04为Indy-Node生成了Docker映像，但是必须从源代码构建libsodium。您可以在此处看到源dockerfile，尽管有些git URL已被构建脚本替换：https://github.com/PSPC-SPAC-buyandsell/von-image/blob/master/node-1.9/Dockerfile.ubuntu

[最终图像在https://hub.docker.com/r/bcgovimages/von-image/tags（节点-*图像，最新为bcgovimages/von-image:node-1.12-2）] >>

我相信Indy-Node团队不久将针对测试中使用的图像更新到20.04。
