How to upgrade to Debian 13 (Trixie)

Consider using tmux for a safe and persistent shell.

sudo apt update
sudo apt upgrade
sudo apt full-upgrade
sudo apt autoremove

sudo sed -i 's/bookworm/trixie/g' /etc/apt/sources.list
sudo sed -i 's/bookworm/trixie/g' /etc/apt/sources.list.d/*.list

sudo apt update
sudo apt upgrade
sudo apt full-upgrade
sudo apt autoremove

If prompted for character set to support and unsure, select Latin1 and Latin5 - western Europe and Turkic languages.

Review configuration.

If you want a thorough upgrade, reboot:

sudo reboot
