Ubuntu 23.10 Mantic Minotaur is an interim release, originally released on 12 October 2023, and supported for nine months until July 2024.This release incorporates a new App Center built in Flutter that replaces Ubuntu Software, TPM disk encryption, a separated firmware updater, Netplan as the default network configuration tool, and support for Raspberry Pi 5. The installer can now update itself, support guided ZFS installation, and defaults to a minimal installation, which doesn’t include apps deemed non-essential such as LibreOffice, Mozilla Thunderbird, Rhythmbox, and Calendar. Out-of-the-box support for installing .deb package files graphically was removed; however, the dialog for choosing an alternative app to open the file still recommended opening with the App Center. This would lead to uproar when the behavior was left unchanged in the next release.
This version also includes an upgrade to GNOME 45, which replaces the top-left corner’s app name display with an indicator of the workspace being used, adds a camera usage indicator, a new camera app named “Snapshot”, and a new image viewer app. Sidebars are now as tall as their windows as part of design polishing.
Approximately 6 hours after release, the download link to Ubuntu 23.10 was removed due to hate speech in an externally-sourced Ukrainian translation of the installer. Downloads were restored 4 days later.
