It used to be that I could leave the old kernel installed. After a third kernel got installed, an "apt autoremove" would remove the old one. I found that much more convenient than what I currently have to do, which is (remember to) manually delete the old kernel before installing the third one. But it requires space in /boot for 3 images. best wishes, mike
