Update Ubuntu Before Upgrading to Ubuntu 24.04
Preparing Your System for Upgrade
Initiate the upgrade process to Ubuntu 24.04 by first updating your current Ubuntu system. This is a fundamental step, ensuring your system aligns with the latest updates, which is critical for a trouble-free upgrade.
Updating Package Lists and Upgrading Packages
To update the package lists for upgrades, use the apt command:
sudo apt update
This command retrieves the latest list of updates from your configured repositories, a necessary step for your system to recognize all new software versions.
Then, to upgrade all installed packages to their latest available versions, execute:
sudo apt upgrade -y
Using the -y
flag automatically confirms the installation of updates, facilitating a more efficient process. This step is crucial in ensuring your current software is fully updated, setting a stable base for the upgrade to Ubuntu 24.04.
Performing a Distribution Upgrade
As an optional but recommended action, run:
sudo apt dist-upgrade
The dist-upgrade
command adeptly handles changes in new package versions and manages any arising conflicts. It offers a more sophisticated approach than the basic upgrade command, adept at managing complex package dependencies. This step is especially significant for major system upgrades, ensuring all packages are optimally prepared for Ubuntu 24.04 LTS.
Upgrade to Ubuntu 24.04 via Desktop GUI Method
Initiating the Upgrade Process
Start your upgrade to Ubuntu 24.04 by opening the terminal with CTRL+ALT+T. In the terminal, enter:
sudo update-manager
This command opens the Update Manager, which is essential for managing updates and upgrades in Ubuntu.
Using the Development Release Option
If the Update Manager doesn’t present an upgrade option, compel it to search for the latest development release, including new LTS versions like Ubuntu 24.04, with:
sudo update-manager -d
The -d
flag directs the Update Manager to look for development releases.
Ensuring Update Manager Core is Installed
Should the Update Manager not launch, confirm the presence of the update-manager-core
package, or install it using:
sudo apt install update-manager-core -y
The -y
flag automates confirmation, streamlining installation.
Upgrade Prompt
Once you connect to a stable internet, the Update Manager window will appear. Click on the ‘Upgrade…’ button to initiate the upgrade process.
Troubleshooting
If the upgrade prompt fails to appear, it might be due to outdated packages. Ensure your system is fully updated for the Upgrade Manager to detect Ubuntu 24.04 and begin the upgrade.
