On my desktop machine (Kubuntu 16.04LTS I think), I set up /boot too small, because at one point my distro automatically removed old kernels, so there wasn't need for much space. But that doesn't happen anymore, so sometimes it fills up. Well it turned out that when I went to delete some of the older kernels, it turns out I was actually running one of them, and now Grub is very unhappy. This is dual boot with Windows, which still works. I'm sending this from my laptop. It's now like 2AM so I need to get to bed. I have tried a bunch of things, but clearly I didn't exhaust Google yet. I'm posting this in case someone who has experience in this can just head me towards The One True Way to fix this. I will continue trying tomorrow though. Grub is looking for vmlinux-4.4.0-28-generic, and I have vmlinux-4.4.0-34-generic and vmlinux-4.4.0-36-generic still. - I tried booting from USB, mounting root and boot, and simply symlinking the 36 kernel to 28. I ended up at some initrd prompt. - I tried both mechanisms at http://askubuntu.com/questions/28099/how-to-restore-a-system-after-accidentally-removing-all-kernels (tl;dr mount some of the root partition then chroot to |||it and run "| |apt-get install linux-image-generic"). It reported endless dependencies that couldn't be met. I have a feeling I may need to try this again after finding the magic command to remove anything from the "scheduled to be installed" list. | |- I tried the above chroot thing, then https://statusq.org/archives/2012/10/24/4584/ to |grub-set-default to a kernel I *do* have, but it still looked for 126.96.36.199. Maybe I did the chroot wrong? Maybe I forgot a step? I suppose the nuclear option would be to reinstall over the current install without reformatting and maybe kinda it may work. I welcome other ideas to try. Like I said I will continue to work on this though. Far from waving the white flag but close to my bed. Thanks.
