package frontaccounting (not installed) failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

I didn't see the window asking me about the web server, so, since the installation wouldn't finished, I stopped Ubuntu software center, then desinstall frontaccounting, then tried to install it again but I got an error message. I tried several times to uninstall and install, not to avail.
