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
  95ab9a408a3e94564f5a9bfb6e82c9dc371f32e92004ee98acbf64b431c93e81  /usr/share/keyrings/tissamba.gpg
echo "deb [signed-by=/usr/share/keyrings/tissamba.gpg] https://samba.tranquil.it/debian/samba-4.22/ $(lsb_release -c -s) main" > /etc/apt/sources.list.d/tissamba.list

Warning

For Samba versions earlier than 4.22.7 please use this gpg key

wget -qO- https://samba.tranquil.it/tissamba-pubkey-2017.gpg | tee /usr/share/keyrings/tissamba.gpg > /dev/null

  • 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
