The second release candidate of the Debian GNU/Linux 10 installer is now available for testing

The Debian Installer team[1] is pleased to announce the second release
candidate of the installer for Debian 10 "Buster".


Improvements in this release
============================

* choose-mirror:
- Update Mirrors.masterlist.
* cryptsetup:
- New section “Unlocking LUKS devices from GRUB” pointing to:
https://cryptsetup-team.pages.debian.net/cryptsetup/encrypted-boot.html
* debian-archive-keyring:
- Add Buster keys (#917535, #917536).
* debian-cd:
- Create images to fit on 16G USB sticks too (for amd64 and i386).
- Tweak package selection to make the multi-arch firmware netinst
fit on CD media again (needs a 700MB CD-R): Don't include 686
PAE kernels on these CDs.
- Tweak ordering of snapshot URLs in jigdo images to remove load
on snapshot.debian.org.
* debian-installer:
- Add haveged-udeb [linux] to avoid entropy starvation issues
(#923675). Those could affect HTTPS connections, SSH keypair
generation, etc.
- Bump Linux kernel ABI from 4.19.0-4 to 4.19.0-5.
- Add œ/Œ glyphs for the French translation.
- Update size limits.
- Relabel “Dark theme” into “Accessible high contrast” (#930569).
- Compress armhf u-boot images with “gzip -n” to avoid embedding
timestamps which cause reproducibility issues.
* espeakup:
- Wait longer for sound cards.
* grub2:
- Make grub-efi-*-bin recommend efibootmgr, for debugging purposes.
- Make grub-efi work on armhf too (upstream fixes for alignment
bugs).
* installation-guide:
- Add the partman-auto-lvm/guided_size setting to the example
preseed config file (#930846).
* libdebian-installer:
- Enlarge maximum line length in Packages and Sources files
(#554444).
* lowmem:
- Update size limits.
* network-console:
- Fix gen-crypt segfault, which prevented remote installations due
to a missing password for the “installer” user (#926947, #928299).
* openssl:
- Ship an openssl.cnf in libssl1.1-udeb, fixing wget's TLS issues
in the installer (#926315).
* partman-auto:
- Tweak Arabic translation to avoid a hang at the hard disk step
(#929877).
* preseed:
- Update auto-install/defaultroot, replacing stretch with buster
(#928031).
* rootskel:
- Start haveged when appropriate, to avoid entropy starvation
(#923675). This means when the haveged binary is available, and
when there's no hardware RNG available.
- Update size limits for the graphical installer.


UEFI Secure Boot updates
========================

Debian's Secure Boot setup is still being polished, the main updates
are summarized below.

* debian-installer:
- Add shim-signed and grub-efi-ARCH-signed to build-dependencies
for amd64/i386/arm64.
- Use the signed shim and grub packages for all 3 arches for EFI
images.
- Fix the netboot setup for signed grub images to match the
previous setup and the existing documentation (#928750).
* grub2:
- Generate a specific signed netboot image for d-i to use (#928750).
- Add cpuid, play, ntfs modules to signed UEFI images (#928628,
#930290, #923855).
- Deal with --force-extra-removable with signed shim too (#930531).
