Debian 13 "trixie" released press@debian.org
August 9th, 2025 https://www.debian.org/News/2025/20250809
------------------------------------------------------------------------
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 [1] and the Debian Long Term
Support [2] 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
over 70,000 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.
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
* Emacs 30.1

* Rustc 1.85
* Samba 4.22
* Systemd 257
* Vim 9.1
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 [3] 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),
* 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.
If you simply want to try Debian 13 "trixie" without installing it, you
can use one of the available live images [4] which load and run the
complete operating system in a read-only state via your computer's
memory.
4: https://www.debian.org/CD/live/
These live images are provided for the amd64 and arm64 architectures 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 [5]
and the live install images [6] sections of the Debian website. Multi-
architecture Debian "trixie" container images are also available on
Docker Hub [7]. 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
Download [8] such as: Blu-ray Disc, DVD, CD, USB stick, or via a network
connection. See the Installation Guide [9] for more details.

9: https://www.debian.org/releases/trixie/installmanual
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 [10]
(the recommended method), jigdo [11], or HTTP [12]; see Debian on
CDs [13] for further information. "trixie" will soon be available on
physical DVD, CD-ROM, and Blu-ray Discs from numerous vendors [14] too.

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:
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 [15] 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 [16].

https://www.debian.org/releases/trixie/release-notes/upgrading.html#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 [17] man page.
17: https://manpages.debian.org/trixie/ldap.conf.5
We have documented this and other possible issues at 5. Issues to be
aware of for trixie [18] in the release notes. You're advised to read
that before upgrading.
18: https://www.debian.org/releases/trixie/release-notes/issues.html
As always, Debian systems may be upgraded painlessly, in place, without
any forced downtime, but it is strongly recommended to read the release
notes [19] as well as the installation guide [20] 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.
