Comment # 6 on bug 945821 from Stakanov Schufter

I am having here a problem. Did you mean install mode or upgrade mode from the
dvd. From upgrade mode it tells me that upgrading this product is not possible
because not compatible. When I drop to shell via the "interrupt installation"
then expert mode, switch to console:
I get the root prompt. When opening it tells me:
bash: cannot set terminal process group (-1): inappropriate ioctl for device
bash: no job control in this shell
when:
save_y2logs /tmp/y2logs.tgz
bash: save: command not found

when 
save y2logs /tmp/y2logs.tgz 
bash: save: command not found

So I am doing something wrong from the installer to the console I would guess.
It sees the lv and calls it with the right name leap42.1
So the lv exist, it asks for the password correctly to decrypt beforehand. 

What should I try now?
