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:

      Yes, it gives an error very similar to running sudo apt upgrade, in fact running this command is what triggers the “Low Disk Space on “boot”” warning.

        You could try apt remove linux-image-5.11.0-44-generic to delete an old kernel manually. The upgrade and autoremove again.

          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

            Removing linux-image-5.11.0-43-generic 

You are running a kernel (version 5.11.0-43-generic) and attempting to remove the same version.                     

This can make the system unbootable as it will remove /boot/vmlinuz-5.11.0-43-generic and all modules under the

            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?

                This means you run version 5.11.0-43-generic

                Try removing linux-image-5.11.0-40-generic, which is the oldest version in your screenshot

                  sudo apt remove linux-image-5.11.0-40-generic

                  I don’t use a debian based distro now, so you should probably wait until someone else says doing this is safe

                  Okay, but once I removed what do I do? Because otherwise I will have an OS without its kernel, which is not nice.
