Hey, I've just built a script to build each debian flavour in separate directories, and it works fine now.
The reason seem to be that "lb clean --all" doesn't clean enought to change debian's flavour. Maybe a bug to be reported ? Still, I've the workaround I want, thanks. > i noted the "--debian-installer-distribution daily" in the command > line.. i suggest set all need parameters and setup the "sid" Using "-debian-installer-distribution buster" makes a fatal error about kernel modul not being installed, the daily thing is a workaround already ^^'
