Debian Installer Trixie RC 2 release

July 2nd, 2025

The Debian Installer team is pleased to announce the second release candidate of the installer for Debian 13 Trixie.

Improvements in this release

apt-setup:
- Disable cdrom sources if installation medium is not a real CD (USB stick, SD card, ISO file), because APT cannot use it after the installation (#1102140, #1103650).
- Allow preseeding extra options for the local sources.list lines.
busybox:
- Remove wget applet (#1107392).
choose-mirror:
- Update Mirrors.masterlist.
debian-cd:
- Record which firmware packages are embedded in the modified initrds (#1106005).
- Make sure systemd-cryptsetup is available (#1092977).
debian-installer:
- Bump Linux kernel ABI to 6.12.33+deb13.
- Fix Japanese rendering support, with many thanks to Kentaro HAYASHI: add fonts-motoya-l-cedar-udeb to gtk-common (#1037256).
- Stop setting DPKG_UNPACK_OPTIONS = --force-overwrite (#1107392).
- Improve support for speech synthesis, embedding some i915-related modules on amd64, for graphical targets.
grub-installer:
- Set force-efi-extra-removable to "true" by default in some cases, which should help in cases where EFI firmware does not manage EFI boot variables properly.
partman-crypto:
- Install systemd-cryptsetup alongside cryptsetup-initramfs. While the latter is sufficient if one picks guided partitioning with an encrypted LVM layout, other use cases might require the former, originally bundled together within systemd (#1092977).
rescue:
- Add suport for rescuing btrfs systems installed via the Calamares installer found on Debian Live images.
rootskel-gtk:
- Adapt installer banner image to the most recent iteration of the Ceratopsian theme.
- Fix Japanese rendering support by switching from VL Gothic to MotoyaLCedar, also bumping font size (#1037256).
systemd-boot-installer:
- Install shim-signed on amd64/arm64 to enable Secure Boot.

Hardware support changes

console-setup:
- Add support for Apple MTP keyboard and Apple SPI Keyboard, as found on ARM-based Apple laptops like M1 MacBook Pro and M2 MacBook Air (#1108360).
linux:
- [amd64] Add drivers/pinctrl/intel to kernel-image udeb (#1106658).
