Upgrading to Ubuntu 23.10

Existing Ubuntu desktop users may receive prompts when the upgrade is available. These prompts should be displayed a few days after the official release announcement. Users may speed this up by checking for updates manually.

It is recommended to run the following commands to make sure that software is up to date before proceeding with the installation of the new Ubuntu version:

” sudo apt update sudo apt upgrade “

Once done, run the Software Updater, which you find in the application menu. Note that you may make a change in the application’s configuration in order to get interim release (those ending with *.10) upgrade prompts.

Select the Updates tab in the preferences and switch “notify me of a new Ubuntu version” to “for any new version”.

If you encounter any issues after upgrading to Ubuntu 23.10, please consult the release notes or contact the Ubuntu community for support.
