Ubuntu 21.10 Impish Indri Support Ends on July 14 2022

Last updated: June 4, 2022 — Leave a comment

Still working on Ubuntu 21.10? It’s time to upgrade to Ubuntu 22.04 LTS, because it will reach end of life in next month.

Ubuntu 21.10, code-name “Impish Indri”, was released on October 14, 2021 as a short-term release with 9-month support.

Support of this Ubuntu edition will end soon. At that time, there’s no longer package updates and security fixes. Also, Ubuntu PPAs, software developers, as well as other software sources will (or has already) stop updating for 21.10.

To keep safe and get updated software packages, you may either upgrade to Ubuntu 22.04 or do a fresh install of Ubuntu 20.04. Both are long term support releases with 5-year support from their release date. Ubuntu 22.04 is recommended, though it still has various compatibility issues with old applications.

Download / Upgrade to Ubuntu 22.04

If you would like to do a fresh install of Ubuntu 22.04, download the iso image from the official website:

Download Ubuntu

And, here’s a step by step guide that could help you to install Ubuntu 22.04 from an USB stick.

To upgrade from Ubuntu 21.10 to Ubuntu 22.04 LTS, you may either follow the official documentation with basic info. Or, follow this step by step upgrade guide which’s written for Ubuntu 20.04 but also works for 21.10 and will upgrade directly to the final release of Ubuntu 22.04.

How to Upgrade from Ubuntu 15.04 to Ubuntu 15.10

Last updated: October 15, 2015

The Final release of Ubuntu 15.10 Wily Werewolf will be out in a few days on October 22. Below is how to upgrade your existing Ubuntu 15.04 to Ubuntu 15.10.

Preparation

1. Backup Data. You should back up your important documents, files, bookmarks, etc.

2. Disable PPAs. Some PPAs may cause the upgrade fail, so do disable all third-party PPAs in Software & Updates -> Other Software tab.

3. Uninstall video driver. If you’ve manually installed proprietary drivers directly from the manufacturer’s website, then before upgrading I recommend you removing these drivers first and reverting to the open-source drivers.

Upgrade Ubuntu Desktop:

1. Open terminal from the Unity Dash, App Launcher, or via Ctrl+Alt+T shortcut key. When it opens, run command to update your system:

sudo apt-get update; sudo apt-get dist-upgrade

2. After that, launch Software Updater via below command:

sudo update-manager -d

Below window should pop-up and prompt that Ubuntu 15.10 is available for upgrade:

Click the Upgrade button and confirm again in next window. Software Updater will fetch and install the files and prompt you to remove unnecessary applications.

Restart your computer once the upgrade process finished.

Upgrade Ubuntu Server:

1. Backup your configuration files if you’re running any services on Ubuntu server.

2. install the update-manager-core via command: 

sudo apt-get install update-manager-core

3. Edit the config file via below command to make sure there a line says “Prompt=normal” (without quotes):

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

After editing, press Ctrl+X -> type y -> finally hit Enter to apply changes.

4. Finally upgrade Ubuntu Server via command:

sudo do-release-upgrade -d

Follow the on-screen prompts and done!.
