Debian 11 Bullseye Released – Download DVD ISO Images

The Debian Linux operating system distribution is in the limelight for another significant stride. As of August 14th, 2021, it has successfully transitioned from Debian 10 Buster to the new and improved Debian 11 Bullseye. It is a stable version that accommodates various desktop applications and environments.

Debian Supported Desktop Environments

Expect it to be compatible with the following desktop environments.

  • KDE Plasma 5.20
  • Gnome 3.38
  • LXQt 0.16
  • LXDE 11
  • Xfce 4.16
  • MATE 1.24

Debian 11 Bullseye Interesting Improvements

Unlike Debian “buster”, Debian “bullseye” has more software packages to offer its users. It presents 11294-plus new packages out of 59551-plus total packages.

Most of this distribution’s software packages are either updated or upgraded with 16% of Debian “buster” packages excluded in Debian “bullseye” due to their obsolete status.

1. Desktop and Other System Applications

Apart from the highlighted desktop environment support, the following productivity application upgrades are available to LibreOffice 7.0, Calligra 3.2, and GNUcash 4.4.

Debian “bullseye” software package update extends to other popular apps like:

  • Apache 2.4.48
  • BIND DNS Server 9.16
  • GIMP 2.10.22
  • Lighttpd 1.4.59
  • MariaDB 10.5
  • Nginx 1.18
  • OpenSSH 8.4p1
  • Perl 5.32
  • PHP 7.4
  • Postfix MTA 3.5
  • PostgreSQL 13
  • Python 3.9.1
  • Vim 8.2.

2. Driverless Scanning and Printing

There is a high likelihood of SANE scanning and CUPS printing which will remove the need for non-free driver software that is bound to specific hardware types.

CUPS Driverless Printing

CUPS and cups-filters implementation of driverless printing already exist as modern printers’ attributes through Ethernet and wireless connections. Debian “bullseye” introduces a cups-daemon recommended package called ipp-usb.

This package takes advantage of modern printers’ IPP-over-USB vendor-neutral protocol. With this protocol in place, driverless printing accommodates USB-connected printers since they are now categorized as network devices.

The ipp-usb daemon is initiated by an ipp-usb systemd service file upon a successful USB-connected printer setup. This device pre-configuration is bound to take place automatically through cups-browsed.

SANE Driverless Scanning

Libsane1, through sane-escl, facilitates the SANE driverless backend. Sane-airscan is another driverless backend option. It is independently developed. Both sane-airscan and sane-escl adhere to the eSCL protocol. However, it is only sane-airscan that is flexible with the WSD protocol. Your Debian 11 “bullseye” system should accommodate these two backends just to be safe.

The WSD and eSCL network protocols condition their USB connection operability to the existence of an IPP-over-USB device. The ipp-usb package in libsane1 leads to the automatic setup of a USB device through a driverless backend driver once the device is successfully plugged into a functional USB port.

3. New Generic Open Command

Debian users get the opportunity to extend their command-line flexibility through the addition of a new interactive open command alias to run-mailcap and xdg-open. It is an additional way of opening default application files from the system terminal for non-GUI display or to be piped to a GUI display app.

4. Control Groups v2

Systemd defaults to cgroupv2 or control group v2 in Debian “bullseye”. It facilitates the provision of a merged resource-control hierarchy. If you feel like going back to the legacy cgroups, you can re-enable them through the availed kernel command line parameters.

5. Persistent Systemd Journal

Systemd defaults to persistent journal functionality in Debian 11. The storage location of these journal files is “/var/log/journal”. In this system, the systemd-journal group and adm members can access and read journal files. This permission setup has zero interference to rsyslog and other traditional login daemon performances.

6. Fcitx 5 Input Method

This new input feature accommodates many languages like Korean, Japanese, and Chinese. This version boasts of better addon support on top of supporting Wayland.

7. Debian Med Blend

With the COVID-19 epidemic still ongoing, the Debian Med team has included a software package in Debian 11 that focuses on sequence-level research of the Coronavirus through referencing epidemiology tools. Search for med-* metapackages for the installation of the Debian Med team’s maintained packages.

8. exFAT Kernel Support

You can now mount eFAT file systems thanks to Debian 11 for being the first Linux distribution to facilitate the feature functionality. Also, exfat-fuse package facilitation of filesystem-in-userspace implementation is no longer a requirement. However, through invoking mount.exfat-fuse helper when an exFAT filesystem is under-mount, filesystem-in-userspace can be re-implemented.

9. Improved Man Page Translations

Projects relating to OpenSSH, util-linux, Mutt, and systemd in languages like Macedonian, Spanish, and French have undergone substantial improvements in terms of their manual pages documentation. With xx being your Debian system’s preferred natural language code, you should run the installation command for manpages-xx to benefit from this feature.
