Hi Sir,

After Installing new kernel name 5.8.11 in loc /usr/src/kernels/linux5.8.11

After reboot, We have notification regarding low disk space

**Message

Low Disk Space on "Filesystem root"

the volume "Filesystem root" has only 0 byte disk space remaing

This message ignore or examine?

How to expend space & resolve issue?

hello sir,

I have installed linux-4.19.159

I had followed the documents and the commands run successfull upto " make module_install ".

when i am going to run " make install " command it shows the below error :

sh ./arch/x86/boot/install.sh 4.19.159 arch/x86/boot/bzImage \

System.map "/boot"

Cannot find LILO.

smailybhatnagar

Hello sir,

I have complied kernel 5.10.8 successfully.

Module_install is successful.

BUt during make install I am facing below issue:

I tried installing kernel 5.10.8

sh ./arch/x86/boot/install.sh 5.10.8 arch/x86/boot/bzImage \

System.map "/boot"

Cannot find LILO.

Kindly help me with it.

rahul

I think it caused by your configuration imported from system.

You should disable your secure boot.

and redo your kernel installation process again from start.

It may good if install your fedora again and then you build your kernal again.

ritde1

What is System.map, how does it work?

ritde1

Solution to: https://www.emblogic.com/forum/discussion/comment/2856#Comment_2856

@smailybhatnagar

sh ./arch/x86/boot/install.sh 5.10.8 arch/x86/boot/bzImage \

System.map "/boot"

Cannot find LILO.

Solution:

1-> dnf install grubby

2-> grubby --update-kernel=ALL

3-> cd /boot/grub2

4-> grub2-editenv grubenv create

5-> grub2-editenv grubenv set default=0

6-> grub2-editenv grubenv list

then make install and proceed with further procedure(do not reboot before completing further procedure).

Issue:

fatal error: openssl/opensslv.h: No such file or directory

25 | #include <openssl/opensslv.h>

Solution:

To install OpenSSL development package on Debian, Ubuntu or their derivatives:

sudo apt-get install libssl-dev

To install OpenSSL development package on Fedora, CentOS or RHEL:

sudo yum install openssl-devel

or

dnf install openssl-devel

spatlou

Issue:

fatal error: gelf.h: No such file or directory

10 | #include <gelf.h>

Solution:

The missing development library file is with the name: elfutils-libelf-devel.

Installing the package with yum or dnf will resolve the above error:

yum install -y elfutils-libelf-devel

Or

for CentOS 8 and newer Fedora versions:

dnf install -y elfutils-libelf-devel

openssl command not found

Solution:

Try

dnf install openssl

if this also does not work and you get the same error then

locate openssl

(this will give you the path at which he openssl is found)

(Add this path to PATH environment Variable)

PATH=$PATH:openssl-path

[Note: Do not chang the tab]

if you are encountering error while building kernel, try dnf search pkgname, half of the errors will be resolved.

After bootup with the new kernel version I was facing these two Error

NOT ALL DISKS HAVE BEEN FOUND
YOU MIGHT WANT TO REGENERATE YOUR INITRAMF

To resolve this I followed these two commands

Regenerate initramfs for the specific kernel version:

Check your current kernel version using uname -r.

Run the following command, replacing <kernel-version> with your actual version:

Bash

dracut --force /boot/initramfs-<kernel-version>.img <kernel-version>

Regenerate initramfs for all installed kernels (optional):

To regenerate initramfs for all kernels, run:

Bash

dracut --regenerate-all --force

Key Points:

Force overwrite: The --force flag ensures the initramfs image is overwritten even if it already exists.

All kernels: Regenerating for all kernels can be helpful if you're unsure which one is causing the issue.

Reboot required: The changes take effect only after a reboot

Kernel Compilation issue in Ubuntu:

If you are compiling the kernel on Ubuntu, you may receive the following error that interrupts the building process:

No rule to make target 'debian/canonical-certs.pem

Disable the conflicting security certificates by executing the two commands below:

scripts/config --disable SYSTEM_TRUSTED_KEYS

scripts/config --disable SYSTEM_REVOCATION_KEYS

after doing update-grub when i am rebooting my system grub menu is not showing up

utkarshraj273

i updated GRUB_TIMEOUT in /etc/default/grub and ran update-grub but still grub menu is not showing up

utkarshraj273

I resolved this issue by editing GRUB_TIMEOUT and GRUB_TIMEOUT_STYLE in /etc/default/grub to 20 and menu respectively

Issue:

fatal error: openssl/opensslv.h: No such file or directory

25 | #include <openssl/opensslv.h>

| ^~~~~~~~~~~~~~~~~~~~

compilation terminated.

To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.

To install OpenSSL development package on Debian, Ubuntu or their derivatives:

$ sudo apt-get install libssl-dev

To install OpenSSL development package on Fedora, CentOS or RHEL:

$ sudo yum install openssl-devel

Edit : As @isapir has pointed out, for Fedora version>=22 use the DNF package manager :

dnf install openssl-devel

Hi All,

I am facing issue while kernel build.I compiled kernel 6.8.8 and it compiled and booted fine but on booting gives an out of memory error no key is working to continue. The detailed error log shows kernel panic. Please help me out in resolving this issue.

fatal error: openssl/opensslv.h: No such file or directory

for Ubuntu use the following command

sudo apt-get install openssl libssl-dev

fatal error: gelf.h: No such file or directory

for Ubuntu:

apt -y install libelf-dev

Hi @Pravjot Sir,

I have kernel ver 5.15.178 install on ubuntu 20.04.

Kernel install successfully. generate initramfs and update grup.

After system reboot we have found error during boot

- error: the initramfs is too large

we able to boot this kernel in recovery mode and kernel panic - not syncing

We check initramfs size around 810 MB

-rw-r--r-- 1 root root 882383965 Feb 15 03:05 initrd.img-5.15.178

Please suggest how to reduce initramfs size and we try many ways but still face issue.

But we able to boot default kernel version during install OS like 5.15.0-131-generic and initramfs size of this kernel around 100Mb

Error :- *** No rule to make target 'debian/canonical-certs.pem', needed by 'certs/x509_certificate_list'. Stop.

For Ubuntu you need to disable Trust Keys

scripts/config --disable SYSTEM_TRUSTED_KEYS

scripts/config --disable SYSTEM_REVOCATION_KEYS

Error :- gawk: not found

For Ubuntu and Debian

sudo apt update

sudo apt install gawk
