Virtualbox 3.0

Fri, 16 Oct 2009 18:42:00 +0100

Following previous posts about installing Virtualbox, here’s the 3.0 update (currently 3.0.8).

If you have a previous version already installed you need to manually install the new one.

Install

Go to System > Administration > Software Sources and Third-Party Software.
Add the following sources for Intrepid (check your distribution here)
Download and register Sun authentication key

1wget -q http://download.virtualbox.org/virtualbox/debian/sun_vbox.asc -O- | sudo apt-key add -

Be sure your source list is updated

1sudo apt-get update

Be sure you have dkms installed (so Virtualbox host kernel is automatically updated as you update your system kernel)

1sudo apt-get install dkms

Install Virtualbox 3.0

1sudo apt-get install virtualbox-3.0

Logoff and login again
Start Virtualbox at Applications > System Tools > Sun xVM VirtualBox
If you want you can optionally register your VirtualBox installation
If you have a Windows Virtual Machine don’t forget to install the Guest Additions (after starting the virtual machine go to Devices > Install Guest Additions).

Recovering the update-notifier icon in Ubuntu 9.04

Mon, 08 Jun 2009 17:03:00 +0100

If you have installed Ubuntu 9.04 you probably noticed by now that the update-notifier icon no longer appears when there are new updates available. Instead the Update Manager window opens.

This may be a problem if you don’t notice that window and shutdown your system. After that you have to wait for new updates (and notice the Update Manager window that time) or manually look for updates.

To get the update-notifier icon just run the following:

Installing Ubuntu 9.04 Netbook Remix (Asus Eee 1000HE)

Tue, 05 May 2009 20:24:00 +0100

I have a new Asus Eee 1000HE. It came with Windows XP, but I want to try out Ubuntu Netbook Remix.

The eee don’t have an optical drive, so we need to install it using an usb drive.

The goal is dual booting Windows XP and Ubuntu. I want Eee to become my main Windows machine; this will allow me to format my Desktop machine to have only have Ubuntu (next release with default ext4 filesystem). I use Windows only to sync my iPod Touch so, this is a great solution.

Upgrading to Ubuntu 9.04 Jaunty Jackalope (on the Desktop)

Mon, 27 Apr 2009 22:01:00 +0100

After my laptop, is time to upgrade my main machine whith Ubuntu 9.04, codename Jaunty Jackalope.

I will be the using the 32 bit alternate cd to upgrade. This means that the upgrade will have a cd image as his source, and not the Internet. This way it’s much faster, I think.

I shouldn’t do this during the week, but… oh well…

Before you start

Check for updates using Update Manager (be sure to have all the available upgrades done)
Backup your data
Check the Release Notes
Download Ubuntu (I used the Text based “alternate installer” installation disk link to get the alternate image)
Check the file hash (example: md5sum ubuntu-9.04-alternate-i386.iso) and compare it to UbuntuHashes
Be sure to upgrade from Ubuntu 8.10.
Have a burned Live CD laying around, just in case.
Use Gmount-iso to mount the iso file. This way cd could be mounted without having to burn a cd.

Install

In the Terminal, go to the cd mount point (example: /media/cdrom) and type:

Upgrading to Ubuntu 9.04 Jaunty Jackalope

Fri, 24 Apr 2009 11:29:00 +0100

Yesterday Ubuntu 9.04, codename Jaunty Jackalope, was released.

Time to upgrade :-) First in my laptop.

I will be the using the 64 bit alternate cd to upgrade. This means that the upgrade will have a cd image as his source, and not the Internet. This way it’s much faster, I think.

I considered a clean install in order to create ext4 partitions, but after reading around I decided not to, because I saw some “your data may be lost” comments.
