So I've been trying to update/upgrade my system/applications for the last few days and it has been erroring, I ignored it and now when I try to sudo apt upgrade it tells me that I have "Low Disk Space on "boot" The volume "boot" has only 0 bytes disk space remaining."
What happens when I run sudo apt upgrade:
user@user:~$ sudo apt upgrade

Screenshot of /boot:
I am running elementary OS 6.1 Jólnir, built on Ubuntu 20.04.3 LTS using the Linux kernel 5.11.0-43-generic.
Yep either this or expand your boot partition.
Ive sometimes had to boot into a livecd and then delete the old kernel images cos the system wouldn't boot
This happens when I run that command, it scares me, will something break? Is it better to expand my boot partition?
You should be OK as long as you rerun apt upgrade and/or update-initramfs so it properly installs the new kernel.
So, as soon as I run the command to remove that kernel y run sudo apt upgrade or update-initramfs and that's it? How do I know if I have any other old kernel installed?
