now, I want to launch the setup again, but it tell me

ERROR: BlueMind Installer can't upgrade an already installed BlueMind !

Setup process have not reached web interface. Nothing where installed.
How can i launch setup process again ?

thanks by advance.

Response to myself and sharing to all…

If you want to launch again a failed installation, you have to clean or remove /var/spool/bluemind-pkgs/

sudo mv /var/spool/bluemind-pkgs/ /var/spool/bluemind-pkgs-bkp/

It worked for me… :slight_smile:
