Hello @abhaypokharkar

Hi there,

The error messages you’re seeing indicate that the repositories for Ubuntu 23.10 are no longer available at the specified URLs. This is expected behavior when a version of Ubuntu reaches its end of life (EOL).

Ubuntu 23.10 is not a long-term support (LTS) version, so upgrading to 24.04 LTS (Noble) is the best solution for stability and security.

Before attempting a major upgrade on any system, you should make sure you won’t lose data if the upgrade goes awry. The best way to accomplish this is to make a backup of your entire filesystem. Failing that, ensure that you have copies of user home directories, any custom configuration files, and data stored by services such as relational databases.

On a DigitalOcean Droplet, one approach is to power down the system and take a snapshot (powering down ensures that the filesystem will be more consistent). See How to Create Snapshots of Droplets for more details on the snapshot process. After you have verified that the Ubuntu update was successful, you can delete the snapshot so that you will no longer be charged for its storage.

For backup methods which will work on most Ubuntu systems, see How To Choose an Effective Backup Strategy for your VPS.

  • Ensure your system is up-to-date (using old-releases mirrors):
sudo sed -i 's/mirrors.digitalocean.com\/ubuntu/old-releases.ubuntu.com\/ubuntu/g' /etc/apt/sources.list 
sudo sed -i 's/security.ubuntu.com\/ubuntu/old-releases.ubuntu.com\/ubuntu/g' /etc/apt/sources.list 
sudo apt update && sudo apt upgrade -y
  • Run the upgrade command:
sudo do-release-upgrade

If you cannot upgrade right away, you can still get package updates by switching to Ubuntu’s old-releases archive.

Modify your sources.list:

sudo sed -i 's/mirrors.digitalocean.com\/ubuntu/old-releases.ubuntu.com\/ubuntu/g' /etc/apt/sources.list 
sudo sed -i 's/security.ubuntu.com\/ubuntu/old-releases.ubuntu.com\/ubuntu/g' /etc/apt/sources.list

Then run:

sudo apt update && sudo apt upgrade -y

Hope that this helps!
