Upgrading Ubuntu from LTS to Non-LTS Version

Updating your Ubuntu system is usually straightforward, but moving from a Long Term Support (LTS) edition like Ubuntu 22.04 to a non-LTS release, such as 23.10, requires specific steps. Ubuntu doesn't facilitate direct upgrades between LTS and non-LTS releases. This guide will walk you through upgrading from 22.04 LTS to 23.10, addressing potential issues along the way.

Pre-Requisites and Initial Setup

Before diving into the upgrade process, ensure your system is up to date:

sudo apt update && sudo apt -y upgrade

Step 1: Preparing for the Upgrade

Adjust your update manager to permit non-LTS upgrades by modifying the release-upgrades configuration file:

sudo vim /etc/update-manager/release-upgrades

Change Prompt=lts to Prompt=normal to prompt for the latest release.

Step 2: Transitioning to Ubuntu 23.04

Commence the transition to 23.04:

sudo do-release-upgrade -d

Use the -d flag as 23.10 is still in a developer release phase.

Step 3: Addressing Upgrade Hurdles

If the upgrade encounters issues or fails, inspect the upgrade logs:

xdg-open /var/log/dist-upgrade/main.log
xdg-open /var/log/dist-upgrade/apt.log

Resolve any encountered issues. For instance, if facing problems with nautilus:

sudo apt remove nautilus

Complete a software update:

sudo apt update && sudo apt -y upgrade

Handle any packages being "kept back" by manually force-installing them.

Step 4: Finalizing the Transition

After successfully upgrading to Ubuntu 23.04, perform system cleanup:

sudo apt autoclean

Verify the version:

lsb_release -a

Step 5: Repeat the Process

Proceed with the second phase of the upgrade:

sudo do-dist-upgrade -d

Ensure smooth progression through the upgrade process, responding to prompts as necessary, until reaching the final reboot.
