Update Ubuntu Before Upgrading to Ubuntu 24.04
Preparing Your System for Upgrade
Update your existing Ubuntu system before beginning the upgrade process to Ubuntu 24.04. Making sure your system is up-to-date with the most recent updates is a basic step that is essential for a trouble-free upgrade.
Updating Package Lists and Upgrading Packages
Use the apt command to update the package lists in preparation for upgrades:
sudo apt update
This command gets your configured repositories to provide the most recent list of updates, which is a prerequisite for your system to detect any new software versions.
Next, to update every installed package to the most recent version that is accessible, run:
sudo apt upgrade -y
Installing updates is automatically confirmed when the -y flag is used, making the process run more smoothly. This is a critical step that will guarantee that your current software is up-to-date and provide a stable foundation for the Ubuntu 24.04 upgrade.
Performing a Distribution Upgrade
Run the following as an optional but advised action:
sudo apt dist-upgrade
The dist-upgrade command skillfully handles conflicts that may arise and adapts to changes in new package versions. It provides a more advanced method than the straightforward upgrade command and is skilled at handling intricate package dependencies. Making sure all packages are ready for Ubuntu 24.04 LTS is a crucial step, especially for large system upgrades.
Upgrade to Ubuntu 24.04 via Desktop GUI Method
Initiating the Upgrade Process
To begin the Ubuntu 24.04 upgrade, press CTRL+ALT+T to open the terminal. Enter the following in the terminal:
sudo update-manager
To manage updates and upgrades on Ubuntu, run this command to launch the Update Manager.
Using the Development Release Option
If the Update Manager does not offer an upgrade, force it to look for the most recent development release using the following commands, which will also look for new LTS versions such as Ubuntu 24.04:
sudo update-manager -d
The Update Manager is instructed to search for development releases by using the -d flag.
Ensuring Update Manager Core is Installed
If the update manager does not open, check if the update-manager-core package is installed, or use the following instructions to install it:
sudo apt install update-manager-core -y
Installation is made simpler by automating confirmation with the -y flag.
Upgrade Prompt
After you establish a reliable internet connection, the Update Manager window will open. To start the upgrade process, click the "Upgrade..." button.
Troubleshooting
If the upgrade prompt does not show up, out-of-date packages may be the cause. To enable the Upgrade Manager to identify Ubuntu 24.04 and start the upgrade, make sure your system is up-to-date.
Upgrade to Ubuntu 24.04
Step 1: Reviewing Release Notes
The release notes are the first part of the upgrade. Be aware that Ubuntu 24.04 may still be under development at this time. For people who use Ubuntu as their main operating system or in production, this information is extremely important.
Select "Upgrade" to continue.
Step 2: Confirming Upgrade Details and Proceed to Ubuntu 24.04
Details about the upgrade, including new installations and out-of-date packages, are shown on the following screen. Examine this thoroughly to comprehend the upcoming modifications.
To continue, click "Start the Upgrade".
Several minutes will pass, based on the hardware of your system.
Step 3: Removing Obsolete Packages
The system will ask you to uninstall out-of-date packages after the upgrade. Unless there is a specific reason to keep them, choose "Remove" for a cleaner upgrade.
Step 4: Completing the Installation
Most users decide to delete outdated packages after dealing with them. Use "Restart Now" to restart your system to complete the upgrade.

Alternatively, until Ubuntu 24.04 is formally released, utilize the following command:
sudo do-release-upgrade -d
Here, the -d flag is used to update to Ubuntu 24.04 development release. This command walks you through the upgrade process by posing a series of questions.
Proceed with Upgrade to Ubuntu 24.04 Server
After downloading the required files, you'll be asked to upgrade to Ubuntu 24.04 Server, or to use the desktop CLI terminal if you're doing it that way.
Input y to continue:
Removing Obsolete Packages
As with the first desktop upgrade method, a command-line prompt to remove Ubuntu 22.04's leftover obsolete packages will appear in your terminal:
This can be completed later on and is optional. To continue, type y or n:
Restart Ubuntu
A system restart is required after the upgrade is finished. Apply the subsequent command:

Your server will restart with this command, taking effect of all the changes.
Verifying the Upgrade
