Hi,
I can't reproduce this error with the same settings so it doesn't seem to be related to the choices you made in the installer. I'm thinking that something odd must happen before that causing the error.
Please capture the whole output of qlustar-initial-config using
qlustar-initial-config 2>&1 | tee log
and attach that. Maybe there is some error that scrolls by too fast so you missed it.
