Ubuntu 23.10 (Mantic Minotaur) released

Ubuntu 23.10, codenamed “Mantic Minotaur”, is here. This release continues Ubuntu’s proud tradition of integrating the latest and greatest open-source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, partnering with the community and our partners, to introduce new features and fix bugs.

Security takes center stage in this release with experimental support for TPM-backed full disk encryption landing on Ubuntu Desktop. Based on the same architecture as Ubuntu Core, encryption keys are stored in the Trusted Platform Module and only released by authenticated boot software to protect against device tampering.

PPAs are now added as deb822-formatted .sources files where keys are directly embedded into the file’s signed-by field to create a 1:1 mapping between the PPA and its key.

Ubuntu Desktop 23.10 is based on GNOME 45 and sports a brand new App Center built in Flutter. This delivers a fast, intuitive way to manage both snap and deb packages on your machine and lays the groundwork for a richer store experience using snap metadata going forward. This release also sees the return of ZFS guided install, and a change of the default install flow to prefer a streamlined set of default packages.

Ubuntu administrators will benefit from the inclusion of Netplan as the default backend for storing NetworkManager settings, unifying the Server and Desktop networking experience. Fleet management has also been improved with a new `pro enable Landscape` quickstart enrollment feature and the inclusion of certificate auto-enrollment policies for Active Directory as part of ADsys.

Ubuntu 23.10 delivers the latest toolchains and runtimes for Python, Java, Go, C, C++, Rust, and .NET. This release also includes the latest version of `docker.io` and the addition of both `docker-buildx` and `docker-compose-v2` to support Docker developers on Ubuntu.

Finally, we are excited to announce that Ubuntu 23.10 will support the latest Raspberry Pi 5 upon its release later this year.

The newest Edubuntu, Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, Ubuntu Unity, and Xubuntu are also being released today. More details can be found for these at their individual release notes under the Official Flavours section:


Maintenance updates will be provided for 9 months for all flavours releasing with 23.10.
