Status of Debian Edu "Bullseye"

(development started in July 2019)


Instead of the default xfce desktop environment, mate, gnome, lxde, lxqt or kde can be used by editing the kernel desktop parameter (default: desktop=xfce). See the Buster manual installation chapter how to edit kernel command line parameters.

Debian Edu ISOs for 64-bit and 32-bit PCs (both AMD and Intel processors) are available from the usual Debian places.

Download using http

(Replace amd64 with i386 if an image is needed for very old 32-bit PCs.)

Weekly builds using d-i from buster:

Daily iso-cd builds using d-i from unstable (iso-bd images are not built daily):

Download using rsync

Also recommended to update an already existing image.

  • rsync -v --progress cdimage.debian.org::cdimage/weekly-builds/amd64/iso-cd/debian-edu-testing-amd64-netinst.iso debian-edu-testing-amd64-netinst.iso

    rsync -v --progress cdimage.debian.org::cdimage/weekly-builds/i386/iso-cd/debian-edu-testing-i386-netinst.iso debian-edu-testing-i386-netinst.iso

    rsync -v --progress cdimage.debian.org::cdimage/weekly-builds/amd64/iso-bd/debian-edu-testing-amd64-BD-1.iso debian-edu-testing-amd64-BD-1.iso

    rsync -v --progress cdimage.debian.org::cdimage/weekly-builds/i386/iso-bd/debian-edu-testing-i386-BD-1.iso debian-edu-testing-i386-BD-1.iso

Verify the downloaded image file

Detailed instructions for verifying these images are part of the Debian-CD FAQ.

Known problems we want to fix

Known problems that need to be fixed elsewhere

  • LTSP 19.x: 'ltsp image /' fails to generate usable image, see 946946. For a workaround see the bugreport.

  • debian-installer-11-netboot-{amd64,i386} packages do not exist yet.
  • X2Go doesn't register users with utmp/wtmp, see 890517. Remove the killer package (or disable the killer cron job) on the related LTSP server to avoid user sessions to be kicked out.

Known problems we fixed via workarounds, real fix needed elsewhere

  • Mounting removable media (like USB sticks) fails on diskless workstations; for details and workarounds, see 913774.


  • Our documentation could further be improved: eg by proof-reading and improving language+grammar used, by updating outdated entries, etc

Fixed and done

  • Xfce is missing a volume control in the panel, see 913610. [Unlikely to be fixed in Buster.]

  • fetch-ldap-cert should have independent conditions for host and LTSP chroot, see 934380.

  • Fix fetch-ldap-cert to improve security, see 931413.

  • Drop obsolete code in d-i/finish-install, see 923675.

  • Fix sudo-ldap configuration, see 929964.

  • Fix LTSP related PXE configuration, see 928756.

  • Fix Firefox NFS related issue, see 930122.

  • Fix krb5 related logging configuration, see 931366.

  • Set LTSP chroot path in /etc/exports file if LTSP server has i386 arch, see 931680.

  • Include the LDAP server certificate in initial LTSP chroot image, see 932828.

  • Provide Debian Edu RootCA certificate for download, see 933183.

  • Fix loss of dynamically allocated v4 IP address, see 933580.
