My computer asked me if I wanted to upgrade to 20.04LTS. I said OK. It filled up /boot and crashed. I followed some instructions to boot into 2nd-to-last image and delete old kernels. I did that, and deleted the newest kernel that crashed. Then I did sudo do-release-upgrade. It did nothing to the kernel, but now it thinks I have 20.04LTS. I know I don't, because it should be a 5.4 kernel and what I have is

Linux catskills-Z390-AORUS-MASTER 5.3.0-62-generic #56-Ubuntu SMP Tue Jun 23 11:20:52 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

I think I should have something like 5.4.0-26-generic. How do I get there safely?

You have to install the corresponding meta-package by:

sudo apt-get update
sudo apt-get install linux-image-generic

and then to be completely sure install all newest dependencies for 20.04 LTS by

sudo apt-get dist-upgrade

  • Shouldn't the "upgrade" of Ubuntu have done this? If they offer an upgrade, it should work. Why is a manual intervention necessary? – kanehekili Jul 24 '20 at 22:28
  • Per the text of my question, it filled up the /boot partition with new stuff and then crashed in a horrible way. I followed the suggested solution to get past the /boot fail. That left it in a state where it thought it was 20.04 but was running an earlier kernel. Hence the question.
