Ubuntu Lucid Lynx 10.04 has been released since 30 April 2010. It’s been a month now. But some of my friends who are new to Ubuntu still ask me how to upgrade from Ubuntu Karmic Koala 9.10 to Ubuntu Lucid Lynx 10.04.
For the desktop edition, please follow these steps:
- Start the Update Manager (System > Administration > Update Manager)
- The Update Manager should show that a new distribution release (10.04 LTS) is available. Click the Upgrade button to start the distribution upgrade.
- Then just follow the wizard; it will ask for your user password. Then it will download the upgrade package. It will take some time to install.
- After all the packages are installed, it will ask you to restart the system.
- Restart, and you will see the differences. Now your Ubuntu is upgraded to the new version.
For the server edition, please follow these steps:
1. Login as root.
2. Run update:
aptitude update3. Install the package update-manager-core:
aptitude install update-manager-core4. Open the file /etc/update-manager/release-upgrades:
vim /etc/update-manager/release-upgrades5. Check if Prompt=normal is in that file.
6. Run the upgrade script:
do-release-upgrade7. The upgrade script will run and ask you some questions. Just follow the prompts and reboot.
8. Now your Ubuntu has been upgraded.
