The Debian Project has announced the release of the second Release Candidate (RC2) of the Debian Installer for the upcoming Debian GNU/Linux 13 “Trixie” series, slated for public release in late June or early to mid-July 2025. This version introduces several significant enhancements, including the capability to rescue Btrfs systems that were installed using the Calamares installer.

Among the improvements, the installer now supports systemd-cryptsetup alongside cryptsetup-initramfs, and it accommodates Apple MTP and SPI keyboards commonly found in ARM-based laptops like the M1 MacBook Pro and M2 MacBook Air. Additional features include:

  • The addition of drivers/pinctrl/intel to the kernel-image udeb.
  • Support for installing shim-signed on AMD64 and ARM64 systems to facilitate Secure Boot.
  • A refined mechanism ensuring the availability of systemd-cryptsetup.
  • The ability for users to pre-seed extra options for local sources.list entries.

The new release also makes modifications, such as disabling CD-ROM sources if the installation medium is not an actual CD, enhancing the ability to track embedded firmware packages in modified initrds, and upgrading speech synthesis support for graphical targets.

Noteworthy is the maintenance of certain defaults, such as setting force-efi-extra-removable to “true” in specific instances to assist with EFI firmware management issues.

Additionally, improvements have been made to the Japanese rendering support by switching from VL Gothic to MotoyaLCedar fonts, and updates have been applied to the Mirrors.masterlist file.

The Debian Installer Trixie RC2 version, while stable for testing, should not be utilized in a production setting. Users interested in exploring the changes can find more details and testing options through the official Debian website.
