Comment 38 for bug 1675079

Update to comment 37

Issue 2) was my fault of not properly unmarking all components of the kernel, so that some of it kept the "manual" status and prevented removal. But once I severed all those marks, "apt autoremove" could do it's work.

Issue 1) was reported first here:
