Low Disk Space on "boot"

Kromonos@fapsi.be · 3 years ago

Have you tried apt autoremove to clean up old packages?

ghost_laptop@lemmy.ml · 3 years ago

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-5.11.0-43-generic to delete an old kernel manually. Then upgrade and autoremove again.

krolden@lemmy.ml · 3 years ago

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?

linux-image-5.11.0-43-generic

I’ve seen linux-image-5.11.0-40-generic and linux-image-5.11.0-41-generic too. You could try with these one first

ghost_laptop@lemmy.ml · 3 years ago

With what first? Keep in mind that since elementary is built upon Ubuntu LTS I can’t use the newest version of the Linux kernel because it hasn’t been tested and such, maybe I should post on elementary’s subreddit. :/

krolden@lemmy.ml · edit-2 3 years ago

You should be OK as long as you rerun apt upgrade and/or update-initramfs so it properly installs the new kernel.

ghost_laptop@lemmy.ml · 3 years ago

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?

What does uname -a output?

ghost_laptop@lemmy.ml · 3 years ago

Linux device 5.11.0-43-generic #47~20.04.2-Ubuntu SMP Mon Dec 13 11:06:56 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

libinator@lemmy.ml · edit-2 3 years ago

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

libinator@lemmy.ml · 3 years ago

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

ghost_laptop@lemmy.ml · 3 years ago

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