On my Raspberry Pi 4 running Ubuntu Server 20.04:

root@pi4-4gb:~/initramfs# dpkg -l | grep 'linux-image' | cut -c 1-55

ii  linux-image-raspi              5.4.0.1042.77

I regularly run:

sudo update update && sudo apt upgrade && sudo apt dist-upgrade && sudo apt autormeove

Why is it running kernel 5.4.0-1015.15 instead of 5.4.0.1042.77?

Have you made a reboot?

@nobody Sorry, should have mentioned I regularly reboot the device.

what gives `sudo update-grub` and `cat /etc/default/grub` ? Please add this to your question.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
