Backup

First, you must update and upgrade all your system packages to the latest version. Run the following command to update and upgrade all packages:

apt-get update -y
apt-get upgrade -y
apt-get dist-upgrade -y

Next, remove all unwanted packages with the following command:

apt-get autoremove

Next, clean up the APT package cache with the following command:

apt-get clean

Next, restart your system to apply all updates:

reboot

Update to Ubuntu 24.04 using the do-release-upgrade tool

Now we can upgrade to Ubuntu 24.04 using the do-release-upgrade tool. Run this command:

do-release-upgrade

Go through the upgrade steps shown on the screen. The tool will query you for input every now and then and will only continue after you choose/confirm an option.

When the tool is done, reboot your server. If this has not been done during the upgrade process, do it manually:

reboot

Re-enable external repositories

If you had any extra repositories configured, these will be disabled after using the do-release-upgrade tool. To check if you have such repositories, list the content of the sources.list.d directory:

ls -la /etc/apt/sources.list.d/

If there are any .list or .list.distUpgrade files in this directory, check with the maintainer of the relevant repository/repositories to see what the correct configuration if for Ubuntu 24.04 (jammy). After updating the file(s) accordingly, run:

apt update
apt upgrade

Verify Ubuntu 24.04 Upgrade

At this point, your server is upgraded to Ubuntu 24.04. You can now verify it using the following command:

lsb_release -a

You should see the Ubuntu version in the following output:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.1 LTS
Release:        24.04
Codename:       noble
