Hi everyone,

i have installed OpenProject on Proxmox via LXC bare metal on Debian 12 bookworm. With the latest version 15.5.1, everything worked fine.

First, i tried to upgrade my version with

sudo apt-get update && apt-get install --only-upgrade openproject

but failed, due to the fact, that the actual repository is still 15. So i added the current repo to my instance and upgraded to the current version.

wget -O /etc/apt/sources.list.d/openproject.list \
  https://dl.packager.io/srv/opf/openproject/stable/16/installer/debian/12.repo

sudo apt-get update && apt-get upgrade -y

sudo openproject configure

 Well, that totally crashed my instance ! I got the following errors:

Anyone else experienced the same problem? I am glad this wasn´t a production environment, but i am now facing challenges upgrade several of my production instances.

Hope any admin can help me out with this.

Thanks in advance,

Ralph
