If you are using Hardy Server or any other older versions of Ubuntu Server, and you want to upgrade to Intrepid Server or any other future latest Ubuntu Server releases, here are the simple steps...

But before that, please take note that upgrade will not take place by default because 8.10 is not a Long Term Support (LTS) release.

Very important, be sure that you have all updates applied to Ubuntu 8.04 LTS before you upgrade to 8.10.

Here are now the steps:

1. Install update-manager-core:
   sudo apt-get install update-manager-core

Sometimes you you want to play some music or video but it doesn't allow you because it asked for some strange codecs that you may not understand :)

Good news is, it relatively easy to download most of them all together.

Here's how:

1. Switch to super user
   sudo -s -H
2. Update and upgrade your present system by using these two separate commands
   apt-get update

   apt-get upgrade

3. Here's now the magic; install the following common codecs
   

Once again, here's my updated simple installation of Apache, PHP and MySQL in Ubuntu 8.04 LTS (Hardy Heron) Server.

1. Install SSH Client and Server (for my remote access)
   sudo apt-get install ssh

2. Install Database Server
   sudo apt-get install mysql-server-5.0

3. Install Apache HTTP Server
   sudo apt-get install apache2

4. Install PHP5 and Apache PHP5 module
   sudo apt-get install php5 libapache2-mod-php5

5. Restart Apache
   sudo /etc/init.d/apache2 restart


I was kinda surprise that HyperTerminal is not available anymore in Windows Vista. No problem, I rebooted my notebook to Ubuntu and fire-up minicom.

1. By default, minicom is not installed in Ubuntu, so you need to install it first.
   sudo apt-get install minicom
2. Find the name of your Serial Port
   dmesg | grep tty
   In the output look for something like "tty". The output in my case is like this:
$ dmesg | grep tty
[ 17.341823] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

I’m using right now CentoS 4.4 and PHP5 is not yet part of the rpm package. I can always download the source and compile it or search some pre-pack PHP5 RPM and install it.

Alternatively, here’s how to do it using the good old yum one liner command.

1. Edit CentOS-Base.repo
   vi /etc/yum.repos.d/CentOS-Base.repo
2. Enable CentOSPlus by changing:
   
#additional packages that extend functionality of existing packages
