Upgrading to Ubuntu 9.04 Jaunty Jackalope (on the Desktop)

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.

Upgrading to Ubuntu 9.04 Jaunty Jackalope

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.

ext4 is not the default filesystem in Ubuntu 9.04, so you don't need to think about it. Clean intall or upgrade you're good to go.

Virtualbox 2.2

Following previous posts about installing Virtualbox, here's the 2.2 update (currently 2.2.0).

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

The most exciting addition is 3D acceleration for Linux guests, ie, Compiz. Yes sir :-)

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
$ wget -q http://download.virtualbox.org/virtualbox/debian/sun_vbox.asc -O- | sudo apt-key add -
  • Be sure your source list is updated
$ sudo apt-get update
  • Be sure you have dkms installed (so Virtualbox host kernel is automatically updated as you update your system kernel)
$ sudo apt-get install dkms
  • Install Virtualbox 2.2
$ sudo apt-get install virtualbox-2.2
  • Logoff and login again
  • Start Virtualbox at Applications > System Tools > Sun xVM VirtualBox
  • 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).
