As of July 11, 2024, all flavors of Ubuntu 23.10, including Edubuntu 23.10, codenamed “Mantic Minotaur”, have reached end-of-life (EOL). There will be no more updates of any kind, including security updates, for this release of Ubuntu.
If you have not already done so, please upgrade to Edubuntu 24.04 LTS via the Software Updater. If you do not do so as soon as possible, you will lose the ability without additional advanced configuration.
No single release of any operating system can be supported indefinitely, and Edubuntu has no exception to this rule.
Regular Ubuntu releases, meaning those that are between the Long-Term Support releases, are supported for 9 months and users are expected to upgrade after every release with a 3-month buffer following each release.
Long-Term Support releases are identified by an even numbered year-of-release and a month-of-release of April (04). Hence, the most recent Long-Term Support release is 24.04 (YY.MM = 2024.April), and the next Long-Term Support release will be 26.04 (2026.April). LTS releases for official Ubuntu flavors (not Desktop or Server which are supported for five years) are three years, meaning LTS users are expected to upgrade after every LTS release with a one-year buffer.
