How to upgrade Ubuntu 9.04 to 9.10

Share Button

Since the release date for Ubuntu 9.10 “Karmic Koala” is tomorrow I will show you how to quickly upgrade in a few simple steps.

First of all we have to do some prep work. Start the Terminal, you can get to it by clicking “Applications” -> “Accessories” -> “Terminal” and a Terminal Window will start. In the Terminal type:

sudo apt-get update

It is always a good practice to update the apt catalogue. Next it is also a good idea to download and install a updated version on the update-manager to do so type:

sudo apt-get install update-manager

Now that this is done we can go ahead and start the update-manager for the option of a Distribution Upgrade, to do so type:

sudo update-manager -d

this will bring up the update-manager.

Now you should see a new option “New distribution release 9.10 is available” and a Upgrade Button. Click on the Upgrade Button and the process starts with displaying the “Release Notes”. I recommend to read this first before you go ahead.

After you’ve done this click on “Upgrade” and the update-manager prepares your system for the Distribution Upgrade.

If you have Third Party Source in your source list like me then you will see this Message that they are disabled for the upgrade process.

Click on “Close” and the update-manager sets up the new software channels.

Wait a few seconds and the update-manager will show a list of packages whose support ended.

Acknowledge this and click on “Close”. Everything is now prepared and update-manager wants to know if you want to start the upgrade process, click on the Button “Start Upgrade”

Now the update-manager is going to download all new packages, this will take some time something between 30 – 60 minutes depending on your Internet speed.

right after the download the update-manager goes over to the installation of the new packages.

During the installation process the update-manager will ask a few question to the packages that will be installed. You probably won’t see all of those questions, so just disregard those. For the Grub installation just take the defaults.

also for the Postfix installation, just take the defaults

In this stage of the grub installation take the default that says “Keep local version currently installed” so as to cause no additional problems

and another question about grub, just check the installation Hard disk

now the installation process goes on for a few minutes

now the update-manager notifies you about an issue the the RPM Database if you have used it, just click on forward and go on.

you most likely won’t see this. I have an IPsec client installed and update-manager likes to know if it should keep or replace the configuration file. since I have the configuration altered I click on “keep”

I’ll do the same with this one here too and click on “keep”

now that the installation is complete the clean-up process starts

the update-manager want to know now if you would like to remove obsolete packages or not. Your choice!

Well done, upgrade is successfully completed. The last thing that needs to be done is to restart the system. If you did not experience any problems during the upgrade everything should be good and the upgraded system will boot up.

I hope this “how-to” helped you. Don’t forget to subscribe here to my Blog and my Youtube Channel.

VPN into Microsoft PPTP Server with Ubuntu

Share Button

Today I am going to show you how to create a PPTP VPN Connection to a Microsoft PPTP Server. Before we get started you have to collect some information for the Destination VPN Network. You need to know the VPN Gateway Address for example the IP Address or the URL, the User name, Password and optional the Windows Domain Name. One other thing we have to verify is that it is installed. Go ahead and click on “System” -> “Administration” -> “Synaptic Package Manager” in there click on Search and search for pptp and make sure you have pptp-linux & network-manager-pptp installed. If not, do so.

Now that this is done go up to the Panel and look for the Network Manager

Click on it with the left Mouse Button, move all the way to the bottom on “VPN Connections” and roll over to “Configure VPN” Click on it. Now the “Network Connections” Window appears.

Click on the “ADD” Button to add a VPN Connection and select “Point-to-Point Tunneling Protocol

Now the VPN Configuration Window appears and here we need the information you collected earlier.
Enter you VPN Gateway Address, you User name and Password. Optionally you can enter the Windows Domain Name. See Picture:

Now click on the Advanced Button. Under the “Authentication” options it is important that you select everything except “EAP” because its not supported on Windows VPN. Everything has to be selected under “Security and Compression” options, make sure that by “Security” All Available (Default) is chosen and don’t check “Send PPP echo packets” click on OK. See Picture:

Great we are almost done. Select the “IPv4 Settings” Tab. Everything stays default don’t change anything.

One last thing click on the “Routes” Button and also here make sure nothing is configured.

Done! Now go back to the “Panel” click on the Network Manager Icon and Select “VPN Connections” and Roll over to your newly created VPN Connection and click it to Establish Connection to the Remote VPN Network.
