IBM Bluemix, Cloud Foundry and IBM Containers - fatal error: unexpected signal during runtime execution

Whilst tinkering with IBM Bluemix, using the underlying Cloud Foundry (CF) and IBM Containers (IC) capabilities, I was looking to update the IC plugin: -

cf ic update

You are using version 0.8.934 of the IBM Containers plug-in.
Version 0.8.1028 of the plug-in is available for you to install.
Run the "cf ic update" command to update your plug-in to the current version.
You can review the documentation to see the changes that are included in the new version.
https://www.ng.bluemix.net/docs/containers/container_cli_reference_cfic_versions.html

To update the IBM Containers plug-in, run the following commands:

cf uninstall-plugin IBM-Containers
cf install-plugin https://static-ice.ng.bluemix.net/ibm-containers-mac

cf uninstall-plugin IBM-Containers

Uninstalling plugin IBM-Containers...
OK
Plugin IBM-Containers successfully uninstalled.

cf install-plugin https://static-ice.ng.bluemix.net/ibm-containers-mac

which sadly carped out with: -

Thankfully common sense prevailed; I wondered if the problem was due to my being logged into Bluemix and IBM Containers, prior to trying the installation.

I'd previously logged into both services: -

cf login —sso

cf ic login

So I logged out: -

cf logout

Logging out…
OK

and redid from start: -

cf install-plugin https://static-ice.ng.bluemix.net/ibm-containers-mac

**Attention: Plugins are binaries written by potentially untrusted authors. Install and use plugins at your own risk.**

Do you want to install the plugin https://static-ice.ng.bluemix.net/ibm-containers-mac? (y or n)> y

which is nice :-)
