I remember that, in the past, I was several time able to override this
very error by using a -f switch...

It was broke first time I tried to use it more than a year ago ; I don't
clearly remember if it has been fixed at some point in time... I'm
positively sure that I saw the exact same error on other live distros
(possibly Ubuntu but not sure...)

I don't know how to do this, I'm no developper myself...

Kind regards.
