Hello, it is indeed possible. Simply make sure that /etc/openproject/installer.dat has all the values set (easiest way is to perform an interactive install first, then copy and adapt the installer.dat for non-interactive installs). Then run openproject configure and you won't get the wizard.

The -f FILE is only a convenience to set environment variables.

Hi

Thanks you to your shift answer.

So i did a new install (10.3.1) using the Wizzard, and open project starts as expected.

I kept a copy of /etc/openproject/installer.dat, see my installer.dat bellow.

Then i did a new install non interactive using: openproject configure installer.dat

But this time openproject, does not start,  all packages installed normaly once openproject

configure using  the Wizzard, are not installed, see below my rpm -qa result bellow, after

the automatic configuration.

Best Regards
