Indy-node installation fails on Ubuntu

Question

I'm trying to install indy-node on a fresh Ubuntu 18.04 machine in order to create a small network with 4 nodes.

when following the installation instructions I get the following error:

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.

I've tried installing libsodium18 but I get the following error:

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

Likewise, trying to install indy-plenum has a bunch of 'unmet dependency' errors.

**Note:* this is all happens with the following repo:

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

when I try to add the packages for bionic instead of xenial, I get the following error:

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

I have also tried to install indy-node via python + pip, but that doesn't seem to work either.

Has anyone successfully installed indy-node, and if so, can you share the secret?

Answer 1

We've generated Docker images for Indy-Node using Ubuntu 18.04, but had to build libsodium from source. You can see the source dockerfile here although there are git URLs that get replaced by the build script: https://github.com/PSPC-SPAC-buyandsell/von-image/blob/master/node-1.9/Dockerfile.ubuntu

The final images are at https://hub.docker.com/r/bcgovimages/von-image/tags (the node-* images, latest is bcgovimages/von-image:node-1.12-2)

I believe the Indy-Node team are shortly going to be updating to 20.04 for the image used in testing.

Answer 2

The solution in the end was to downgrade to Ubuntu 16.04

Answer 3

There is an Ubuntu 20 image here https://github.com/hyperledger/indy-node-container/blob/main/build/Dockerfile.ubuntu20 . See the commands in the docker file for how to install indy node on a ubuntu 20 installation. It's admittedly quite tricky, fetching packages from all over the place. We are currently working on an ubuntu 22 installation (image).
