How to Upgrade Ubuntu 9.10 (Karmic Koala) to 10.04 (Lucid Lynx)
In my previous post, I wrote showed you how to install Ubuntu 9.10 (Karmic Koala) on your PC. This time we'll be doing an upgrade from that to Ubuntu 10.04 (Lucid Lynx).
Note: You'll need a Wi-Fi connection for this.
Ubuntu 10.04.2 LTS (long term support) is available for download here.
Open System > Administration > Update Manager.
On the Update Manager Window, there's an option called "New Ubuntu release '10.04 LTS' is available". Click the Upgrade button.
Then it will ask "Do you want to start the upgrade?"—click the Start Upgrade button.
When the "Configuring grub-pc" window appears, select "Keep the local version currently installed", which is recommended for systems with Nvdia dedicated graphics.
Remove obsolete packages? I'd recommend keeping them.
Boot using your old GRUB kernel if the latest one fails (I still use the old one).
- You can remove boot kernels through Synaptic Package Manager.
- There's a program called GRUB Customizer. Just install it to modify your boot settings.
