I am trying to install Amazon AWS CloudHSM on AWS EC2 instances running Ubuntu 18.04 LTS.

The instructions from Amazon seem to require an older library libjson-c2, but only the newer library libjson-c3 is available for Ubuntu 18.04 LTS.

Amazon link: https://docs.aws.amazon.com/cloudhsm/latest/userguide/install-and-configure-client-linux.html

I am wondering if anyone can suggest a workaround, since apt install libjson-c2 doesn't seem to work:

# apt install libjson-c2
...
E: Package 'libjson-c2' has no installation candidate

Has anyone had any success using AWS CloudHSM with Ubuntu 18.04 LTS ?

As of today (2018-12-22), Amazon does not yet support Ubuntu 18.04 LTS (confirmed by AWS Support). CloudHSM is only supported for Ubuntu 16.04 LTS.

This is a solution that worked for me. First install libjson-c2 and then install cloudhsm-client. 

    > wget http://mirrors.kernel.org/ubuntu/pool/main/j/json-c/libjson-c2_0.11-4ubuntu2_amd64.deb
    > sudo dpkg -i libjson-c2_0.11-4ubuntu2_amd64.deb
    > wget https://s3.amazonaws.com/cloudhsmv2-software/CloudHsmClient/Xenial/cloudhsm-client_latest_amd64.deb
    > sudo dpkg -i cloudhsm-client_latest_amd64.deb
