EFI partition full

Jumpy

My Solus boot menu shows 3 confs-files for the current kernels and 5 conf-files for lts kernels. How can I remove the old ones?

PS: On my next installation I will make the EFI partition 10 GB instead of the recommended 512 MB!

First you need to mount your boot partition to /boot. It could be anything and there is no way of me knowing for your system. So run df -h and you will get a list of storage devices that are mounted on your system.

Example output:

Filesystem Size Used Avail Use% Mounted on
devtmpfs 4.0M 0 4.0M 0% /dev
tmpfs 24G 145M 24G 1% /dev/shm
tmpfs 9.4G 9.8M 9.4G 1% /run
/dev/sdc3 912G 331G 536G 39% /

In this example / is your root partition, which as you can see is /dev/sdc3 and unless you have some weird manual setup the EFI/boot partition will be on the first partition on the same device so in this case its /dev/sdc1

sudo mount /dev/sdc1 /boot

Now for a script to make it easier. Threw this together and tested it on my system, worked fine. Make sure you have a backup of everything you need. I take no responsibility for this script, run it at your own risk. If you boot multiple Linux distros DO NOT RUN THIS AT ALL as I did not account for that fully or test it.

This script will KEEP the currently loaded kernel, delete everything else, unmount boot partition, update Solus, reinstall the linux-current and linux-lts kernel, check for and fix any broken packages then run all post install triggers. This is all done to make absolutely sure you are on the latest kernel packages by the end of the script.

It will prompt for delete confirmation so pay attention to the prompts.

#!/bin/bash

keepkernel=( $(uname -r | sed s/-.*//) )

deletekernels=( $(ls /boot/EFI/com.solus-project | grep -v $keepkernel) )
deleteloaders=( $(ls /boot/loader/entries | grep -v $keepkernel) )

echo -e "The active kernel has been detected as $keepkernel you will not be prompted to remove files related to this kernel version."

sudo rm -i /boot/EFI/com.solus-project/${deletekernels[*]}
sudo rm -i /boot/loader/entries/${deleteloaders[*]}

echo "Unmounting boot parition..."
sudo umount /boot

echo "Updating Solus..."
sudo eopkg up -y

echo "Reinstalling linux-current kernel package..."
sudo eopkg it --reinstall linux-current

echo "Reinstalling the linux-lts kernel package..."
sudo eopkg it --reinstall linux-lts

echo "Checking for any broken packages."
solchk() {
	output=( $(sudo eopkg check | tee /dev/stderr | grep Broken | awk '{print $4}' ) )
	output_length=${#output[@]}

	if [ $output_length -gt 0 ]; then
		exec sudo eopkg it --reinstall ${output[*]}
	else
		echo -e "\nThere were no broken packages."
	fi
}

solchk

echo "Running all triggers"
sudo usysconf run -f

Reboot and you should be good.

Harvey Thank you so much.

Harvey or use sudo eopkg check | tee /dev/stderr | grep -v OK | awk '{if(NR>1)print $4}'

so you support more than just english as a system language 😛

I hope one day to be able to write like this, I imagine you read terminal like the raining code in the matrix 😃

With this script one theoretically is ok with 512mb efi partition, forever?

It is pretty basic stuff just getting data from a command and then deciding what to do with it.

You shouldn't need this script unless your boot/EFI partition is <512mb or you multiboot an insane amount of operating systems. I personally have never needed it an I've been using Solus for over 5 years.. There might be some edge cases where boot/EFI isn't been cleaned up properly tho but I do not know what is going on there.

Anyway here is a new version that implements Girts suggestion for supporting more than English. As well as guessing what your boot partition is and mounting it. Removing that manual step. The new version should be safe for users who multiboot several Linux distros now.

It also fixes some bugs/logical errors to make sure it actually deletes everything I wanted it to...

However it is still at your own risk. I take no responsibility for its use and one more thing... In testing I realised it will not work if you use LUKs / full disk encryption. So I added a check to exit if LUKs is detected.

#!/bin/bash

getboot=( $(df /boot | grep dev | awk '{print $1}') )
getboot="${getboot%?}1"

keepkernel=( $(uname -r | sed s/-.*//) )

echo -e "\E[1;33m
Before running this script you should backup your system first. The creator of this script accepts no responsibility for its use, you run it entirely at your own risk.
\033[1m\033[0m

The kernel you are currently booted into has been detected as version $keepkernel you will not be prompted to remove files related to this kernel.
This script assumes your boot/EFI partition is on the same storage device as Solus is installed to (Same device as root mount point aka '/').
With this logic we have decided your boot/EFI partition is $getboot

\E[1;33m
Would you like to continue y/n?

if [[ "${getboot[*]}" = *"/dev/mapper/"* ]];
    then
        echo "LUKs detected. This script can not handle automounting boot/EFI on LUKs systems. Exiting..."
    else

            deletekernels=( $(ls /boot/EFI/com.solus-project/* | grep -v $keepkernel) )
            deleteloaders=( $(ls /boot/loader/entries/Solus-* | grep -v $keepkernel) )

            sudo rm -i ${deletekernels[*]}
            sudo rm -i ${deleteloaders[*]}
