Openshift client tools install instructions are wrong for Ubuntu 14.x

Openshift client tools install instructions are wrong for Ubuntu 14.x

Summary

This is a short post to provide a correction to the Openshift getting started instructions for Ubuntu for those using Ubuntu 14.x

Caveat

What follows concerns Ruby and what I know about Ruby could be written on the back of an envelope.

Background

I have an Ubuntu 14.x headless box and I want to make use of the Openshift client tools from it. The Ubuntu machine had never had Ruby installed on it previously and the Openshirt client tools makes use of Ruby so I had to install that.

What do they say ?

Under the heading “Setting up the OpenShift Environment on Ubuntu” you’re told to install Ruby from scratch like this :

$ sudo apt-get install ruby-full rubygems git-core

When I tried that I got :

$ sudo gem install rhc
[sudo] password for rshea:
ERROR:  While executing gem ... (Zlib::DataError)
incorrect header check

So what do you do ?

With help from this Stackoverflow question I adapted the initial command to read

$ sudo apt-get install ruby-full rubygems-integration git-core

Then a bit more

The documentation does tell you to do the following to update your Ruby stack:

$ sudo gem install rubygems-update
$ sudo update_rubygems

It’s a bit odd the way this is tucked away at the bottom as it seems to have been necessary since Ubuntu 11.10. After that I was able to run

$ sudo gem install rhc

followed by

$ rhc setup

After that everything worked as it should.

Avoiding the  “Cannot access virtual machine console. The request timed out” message in VMWare Server Console pane

Disclaimer

This explains how to get around a problem it seems a few people have in VMWare Server. I’ve no idea why it helps but it does !

My Problem

Today I’ve been using VMWare Server for the first time. I set up a new Virtual Machine and wanted to boot Ubuntu Server as a VM. The log messages seemed to suggest everything was going well but when I tried to use the Console within the VMWare Server to configure my new guest OS I would get the message “Cannot access virtual machine console. The request timed out” … again … and … again … and … again ! Very frustrating.

I tried a lot of things – read a lot of documentation and then I stumbled on a way around the problem.

Solution

Within the VMWare Server control panel is a link “Generate Virtual Machine Shortcut”. I’m not sure why I did this but I used that option to generate a URL and then loaded the URL into a different browser. The resulting screen looks pretty similar to the VMWare Server control panel I’d been staring at for a while but for some reason when I tried to use the console it just worked !

As I say I don’t know why but I hope it helps someone who’s bashing their head against this.

Environment

For what it’s worth I’m using Vista Ultimate as the host OS, Ubuntu 8.4.4 Server as the guest OS and VMWare Server 2.0.2.
