How to Fix ‘setkeycodes 00’ and ‘Unknown key pressed’ Console Errors on OpenStack!

Earlier today, I wrote an updated tutorial on using devstack to install OpenStack on a single Ubuntu 16.04 server.  That deployment went so smooth it was no surprise when I ran into a roadblock when trying to console into my first instance.

 

The Problem

 

When accessing the console through the web browser, I wasn’t able to use the keyboard.  Every time I hit any key, these two lines would display in the console:

 

[ 74.003678] atkbd serio0: Use 'setkeycodes 00 <keycode>' to make it known.

[ 74.004462] atkbd serio0: Unknown key pressed (translated set 2, code 0x0 on isa0060/serio0).

Install OpenStack on a Single Ubuntu 16.04.1 Xenial Xerus Server Using Conjure-up

Introduction

 

It’s been some time since I wrote Installing Ubuntu OpenStack on a Single Machine, Instead of 7.  Since then, there have been many updates to both OpenStack, and Ubuntu.

This tutorial will guide you through installing OpenStack on a single Ubuntu 16.04 Server.  I will be installing Ubuntu and OpenStack within a virtual machine hosted on a VMware ESXi Hypervisor, but any fresh installation of Ubuntu 16.04 should work fine, as long as it meets the minimum requirements below.  I will be using conjure-up to install the environment due to the fact that Ubuntu’s Openstack-install package doesn’t working on Ubuntu 16.04.1 at this time.

 

Note:  I have written an updated guide on Installing OpenStack on Ubuntu 16.04 LTS using devstack.  I suggest following that guide unless you have a specific reason for using the conjure-up method.  From my experience, the devstack method requires less resources, runs faster, and performs much better once deployed.

 

Minimum Requirements

 

To install the entire environment on a single physical server or virtual machine, you will need at least:

 

  • 8 CPU’s (vCPUs will work just fine)
  • 12GB of RAM (minimum needed to successfully start everything, more is better)
  • 100GB Disk Space (SSD Prefered, but rotating disk will work)
  • Ubuntu 16.04.1 Xenial Xerus x64 Server(only OpenSSH Server installed)

How-To Install ownCloud 9 / 9.1 / 9.x on Ubuntu 16.04 LTS for the ULTIMATE, Private, Dropbox Clone

Introduction

 

Let’s face it, since the advent of Dropbox, Box, Google Drive and the bazillion other cloud-based file synchronization platforms that have came into existence over the past decade, it’s almost a necessity. For the road warrior, using multiple devices, or even the traditional white-collar worker, having access to all of your files no matter what device you’re using is extremely convenient and adds an enormous productivity boost to our lives. One of my biggest concerns with all of the third-party services, however, is privacy and security. Allowing another entity to store my sensitive data, and trusting they will keep in secure, is pretty scary. Thankfully, there are many options to roll-your-own cloud file synchronization and it really doesn’t take much horsepower on the server side. With a low cost VPS (virtual private server), retired computer at home, or even a $25 RaspberryPi, you can easily build your own Dropbox clone that will put you in control of your own data. Today, I’ll walk you through setting up ownCloud 9.1 on Cannocial’s Ubuntu 16.04 LTS. I will be setting up my cloud on a virtual machine running on VMware ESXi, but the process is very similar no matter what hardware platform you choose. This step-by-step guide assumes you have a plain, unmodified, minimum installation of Ubuntu Server 16.04 LTS, with only SSH access. If you don’t have SSH running, or don’t want to enable it, console access will work just fine. So, lets get started!

 

Installing Prerequisites (Apache/MySQL/PHP)

 

Go ahead and login to your freshly installed Ubuntu 16.04 server.  Be sure to login with a username that has sudoer privileges.  This can be the username you selected during installation or specified when you provisioned your VPS.  Let’s make sure everything is up-to-date before going any further. We will use Aptitude to do so.

 

#  sudo apt-get update

#  sudo apt-get upgrade -y

 

Now we can jump in to the nitty gritty.  There are a few standard prerequisites needed for ownCloud to run.  Most people refer to this as the LAMP stack (short for Linux, Apache, MySQL, PHP).
