Upgrade Ubuntu 22.04 to 24.04 in Ubuntu Server

Since you’re on Ubuntu 22.04 LTS (Jammy Jellyfish), the next LTS release is Ubuntu 24.04 LTS (Noble Numbat). Upgrading between LTS versions is officially supported and relatively straightforward, but it’s important to follow the right steps.

Here’s the recommended process:

1. Update your current system

sudo apt update
sudo apt upgrade -y
sudo apt dist-upgrade -y
sudo apt autoremove --purge -y

This ensures you have all the latest patches for 22.04 before upgrading.

2. Check and install the upgrade tool

sudo apt install update-manager-core

Make sure /etc/update-manager/release-upgrades has:

Prompt=lts

3. Start the upgrade

Since you want latest LTS, run:

sudo do-release-upgrade

If it says “No new release found” (because 24.04 upgrades from 22.04 may not be offered immediately for servers), you can force it:

sudo do-release-upgrade -d

The -d flag forces an upgrade to the latest development release, but after April 2024, 24.04 is considered stable, so it just points to Noble Numbat.

4. Follow the prompts

• The process will download packages, then ask about replacing config files — usually safe to accept the new versions unless you have custom changes.
• Server upgrades will temporarily disable third-party PPAs; you can re-enable them later.

5. Reboot

sudo reboot

6. Verify version

lsb_release -a

You should see:

Distributor ID: Ubuntu
Description:    Ubuntu 24.04 LTS
Release:        24.04
Codename:       noble

💡 Tip: Always back up /etc/ configs and important data before upgrading in case something breaks.

If you like, I can also give you a one-shot upgrade script that safely does all these steps in sequence. Would you like me to prepare that?
