Upgrading a Samba domain controller from Debian11 Bullseye to Debian12 Bookworm

Warning

If you use eth type network interfaces, you should set yourself in grub to keep your interface in eth format.

• You need to reconfigure tissamba.list :

  wget -qO-  https://samba.tranquil.it/tissamba-pubkey.gpg | tee /usr/share/keyrings/tissamba.gpg > /dev/null
  sha256sum /usr/share/keyrings/tissamba.gpg
   bd0f7140edd098031fcb36106b24a6837b067f1c847f72cf262fa012f14ce2dd  /usr/share/keyrings/tissamba.gpg
  echo "deb [signed-by=/usr/share/keyrings/tissamba.gpg] https://samba.tranquil.it/debian/samba-4.20/ $(lsb_release -c -s) main" > /etc/apt/sources.list.d/tissamba.list
  

• Update repositories configuration for NonFreeFirmware, update all PGP keys and all repositories :

  echo 'APT::Get::Update::SourceListWarnings::NonFreeFirmware "false";' > /etc/apt/apt.conf.d/no-bookworm-firmware.conf
  sed -i 's/bullseye/bookworm/g' /etc/apt/sources.list /etc/apt/sources.list.d/*
  

• Update the host:

  apt-get update
  apt-get dist-upgrade
  

Hint

If you have an error during the dist-upgrade, you can use the command “apt –fix-broken install” to fix it.

• Change the ntp configuration with chronyd: configure the NTP service (chrony). This is a very important step !

• Restart the host:

  reboot
  

• Check the version of the Samba server:

  samba-tool --version
