Debian 13
trixie
released
August 9th, 2025
After 2 years, 1 month, and 30 days of development, the Debian
project is proud to present its new stable version 13 (code name
trixie
).
trixie
will be supported for the next 5 years thanks to the
combined work of the
Debian Security team
and the
Debian Long Term Support
team.
Debian 13
trixie
ships with several desktop environments, such as:
GNOME 48,
KDE Plasma 6.3,
LXDE 13,
LXQt 2.1.0,
Xfce 4.20
This release contains over
14,100
new packages for a total count of
69,830
packages, while over
8,840
packages have been removed
as
obsolete
44,326
packages were updated in this release.
The overall disk usage for
trixie
is
403,854,660 kB (403 GB)
, and
is made up of
1,463,291,186
lines of code.
Thanks to our translators who have made the
man
-pages for
trixie
available in multiple languages.
The manpages-l10n project has contributed many improved and new translations
for manual pages. Especially Romanian and Polish translations are greatly
enhanced since bookworm.
All architectures other than i386 now use a 64-bit time_t ABI, supporting dates
beyond 2038.
Debian contributors have made significant progress towards ensuring package
builds produce byte-for-byte reproducible results. You can check the status for
packages installed on your system using the new package debian-repro-status, or
visit
reproduce.debian.net
for
Debian's overall statistics for trixie and newer.
Debian 13
trixie
includes numerous updated software packages
(over 63% of all packages from the previous release), such as:
Apache 2.4.64
Bash 5.2.37
BIND DNS Server 9.20
Cryptsetup 2.7
curl/libcurl 8.14.1

the GNU C Library 2.41
LibreOffice 25.2
Linux kernel 6.12 LTS series
LLVM/Clang toolchain 19 (default), 17 and 18 available
MariaDB 11.8
Nginx 1.26

With this broad selection of packages and its traditional wide
architecture support, Debian once again stays true to its goal of being
The Universal Operating System
. It is suitable for many different
use cases: from desktop systems to netbooks; from development servers to
cluster systems; and for database, web, and storage servers. At the same
time, additional quality assurance efforts like automatic installation and
upgrade tests for all packages in Debian's archive ensure that
trixie
fulfills the high expectations that users have of a stable Debian release.
This release for the first time officially supports the riscv64
architecture, allowing users to run Debian on 64-bit RISC-V hardware and
benefit from all Debian 13 features. A total of seven architectures are officially supported for
trixie
64-bit PC (amd64),
64-bit ARM (arm64),
ARM EABI (armel),
ARMv7 (EABI hard-float ABI, armhf),
64-bit little-endian PowerPC (ppc64el),
64-bit little-endian RISC-V (riscv64),
IBM System z (s390x)
i386 is no longer supported as a regular architecture: there is no official
kernel and no Debian installer for i386 systems. The i386 architecture is now
only intended to be used on a 64-bit (amd64) CPU. Users running i386 systems
should not upgrade to trixie. Instead, Debian recommends either reinstalling
them as amd64, where possible, or retiring the hardware.
trixie
will be the last release for the armel architecture. See
5.1.3.
Last release for armel
in the release notes for more information on our ARM
EABI support.
The Debian Cloud team publishes
trixie
for several cloud computing
services:
Amazon EC2 (amd64 and arm64),
Microsoft Azure (amd64),
OpenStack (generic) (amd64, arm64, ppc64el),
PlainVM (amd64, arm64, ppc64el),
GenericCloud (arm64, amd64),
NoCloud (amd64, arm64, ppc64el)
The genericcloud image should be able to run in any virtualised environment,
and there is also a nocloud image which is useful for testing the build process.
Cloud images provide automation hooks via ``cloud-init`` and prioritize
fast instance startup using specifically optimized kernel packages and
grub configurations.
Want to give it a try?
If you simply want to try Debian 13
trixie
without installing it,
you can use one of the available
live images
which load and run the complete operating system in a read-only state via your
computer's memory.
These live images are provided for the
amd64
architecture and are
available for DVDs, USB sticks, and netboot setups.
The user can choose among different desktop
environments to try: GNOME, KDE Plasma, Cinnamon, MATE, LXDE, LXQt, and Xfce.
Debian Live
trixie
has a standard live image, so it is also possible
to try a base Debian system without any of the graphical user interfaces.
Should you enjoy the operating system you have the option of installing
from the live image onto your computer's hard disk. The live image
includes the Calamares independent installer as well as the standard Debian
Installer. More information is available in the
release notes
and the
live install images
sections of the Debian
website.
Multi-architecture Debian
trixie
container images are also available on
Docker Hub
. In addition to the
standard images, a
slim
variant is available to reduce disk usage.
The Debian Installer and Debian Live Images can now be booted using
HTTP Boot
on supported UEFI and U-Boot firmware.
To install Debian 13
trixie
directly onto your computer's storage
device you can choose from a variety of installation media types to
such as: Blu-ray Disc, DVD, CD, USB stick, or via a network connection.
See the
Installation Guide
for more details.
Debian can now be installed in 78 languages, with most of them available
in both text-based and graphical user interfaces.
The installation images may be downloaded right now via
bittorrent
(the recommended method),
jigdo
, or
HTTP
; see
Debian on CDs
for further information.
trixie
will soon be available on physical DVD, CD-ROM, and Blu-ray Discs from
numerous
vendors
too.
Upgrading Debian
Upgrades to Debian 13
trixie
from the previous release, Debian 12
bookworm
, are automatically handled by the APT package
management tool for most configurations.
Before upgrading your system, it is strongly recommended that you make a
full backup, or at least back up any data or configuration information you
can't afford to lose. The upgrade tools and process are quite reliable, but
a hardware failure in the middle of an upgrade could result in a severely
damaged system.
The main things you'll want to back up are the contents of /etc,
/var/lib/dpkg, /var/lib/apt/extended_states and the output of:
$ dpkg --get-selections '*' # (the quotes are important)
We welcome any information from users related to the upgrade from
bookworm
to
trixie
. Please share information by filing a bug in the
Debian
bug tracking system
using the
upgrade-reports
package with your results.
There has been a lot of development on the Debian Installer since its previous
official release with Debian 12, resulting in improved hardware support and
some very useful new features such as
Improved hardware and software support for speech synthesis
Initial and restricted support for rescuing Debian installed to a btrfs subvolume
Changed default unit from MB to GB when partitioning disks
Disabled cdrom sources if installation medium is not a real CD (USB stick, SD card, ISO file), because APT cannot use it after the installation
Plus support for secure boot with systemd-boot
It is advisable to remove bookworm-backports entries from APT source-list
files before the upgrade; after the upgrade consider adding
trixie-backports
If your APT configuration also involves pinning or
APT::Default-Release
it is likely to require adjustments to allow the upgrade of packages to the new
stable release. Please consider
disabling APT pinning
Under some circumstances, issues might arise during the upgrade process, or
while running
trixie
For instance, the TLS support in the OpenLDAP client
libldap2
and server
slapd
is now provided by OpenSSL instead of GnuTLS. This affects the available
configuration options, as well as their behavior. If no TLS CA
certificates are specified, the system default trust store will now be loaded automatically. If you do not want
the default CAs to be used, you must configure
the trusted CAs explicitly. For more information about LDAP client configuration,
see the
ldap.conf.5
man page.
We have documented this and other possible issues at
5. Issues to be aware
of for trixie
in the release notes. You're advised to read that before upgrading.
As always, Debian systems may be upgraded painlessly, in place,
without any forced downtime, but it is strongly recommended to read
the
release notes
as
well as the
installation
guide
for possible issues, and for detailed instructions on
installing and upgrading. The release notes will be further improved and
translated to additional languages in the weeks after the release.
