Code name for the next major Debian release after bookworm is trixie.

[tteck]

To test out trixie, create a new Debian 12 LXC, then execute the following in the console

sed -i 's/bookworm/trixie/g' /etc/apt/sources.list
apt-get update && DEBIAN_FRONTEND=noninteractive apt-get -o Dpkg::Options::="--force-confold" dist-upgrade -y

reboot

Debian GNU/Linux trixie/sid debian tty1

I might try this on a fully running container with important apps on because I'm a mad man.
Go big or go home I guess.

I'll let you know if Proxmox dies.

EDIT:
Seems to install fine
