lmde kernel upgrade not repopulating /boot

slackbat · 08-13-2023, 05:52 AM

Hi all,

A friend has asked why after a kernel upgrade, are the files within /boot not being replaced or refreshed to show, or point to the newer kernel, and whether this can be done manually.

My friend told me to thank everyone on their behalf for any help

Your friend could save a lot of time by looking things up on the internet. Below is the first hit I got, naturally, there's more:

Hi

My friend thanks you frpm the bottom of his heart, but he tells me that it looks like this is for regenerating a grub config file

Code:

update-grub is a stub for running grub-mkconfig -o /boot/grub/grub.cfg to generate a grub2
       config file.

My friend also wants to tell that his sight is not that good, and even though he did search the web, albeit as much as he could, he did not find how to fix the problem, so he came here as it might be more beneficial.

All the best from me and my friend

Is the new kernel in /boot? Is there a boot partition? Does the system have more than one distro/os installed? Is this a legacy or uefi system? What boot loader does it use?

In addition to answering the questions in post 4, how was the kernel upgrade done? I'm not familiar with LMDE so I don't know which repositories it uses but this is explained for Ubuntu derivatives at the first link below and Debian derivatives at the second link to do it manually.

Hi all from me and my friend,

Here is what my friend reports is in /boot and /usr/src

Code:

System.map-4.19.0-11-amd64  initrd.img-5.10.0-24-amd64
config-4.19.0-11-amd64	    memtest86+.bin
grub			    memtest86+_multiboot.bin
initrd.img-4.19.0-11-amd64  vmlinuz-4.19.0-11-amd64

in /usr/src

Code:

linux-headers-5.10.0-21-amd64	linux-headers-5.10.0-24-common
linux-headers-5.10.0-21-common	linux-kbuild-4.9
linux-headers-5.10.0-24-amd64	linux-kbuild-5.10

and for a bonus /lib/modules

Code:

4.19.0-11-amd64  5.10.0-21-amd64  5.10.0-24-amd64

He informs myself that he is running LMDEm has been updating using mintupdate and apt ; for some reason he has to run apt to update pacjages before being able to run mintupdate.

My freind expresses his thanks for the suggestions, and the links which look really helpful.

All the best from slackbat and friend

What is the apt and mintupdate command to update the kernel,
post the contents of /etc/fstab and the output of

Code:

df -h

It is also worth using dpkg-query to find out the status of this package, i.e. where it got stuck during the process of installation.

For example, if the "lost" kernel is 5.10.0 (as looks to be the case from post 6) use dpkg-query --list "5.10.0".

Hi all from the both of us

Quote:

olorpurple21859 What is the apt and mintupdate command to update the kernel,

From what I can gather, it is just a normal

Code:

apt update

, then with mintupdate its

Code:

mintupdate-cli upgrade

as the graphical front end is flaky.

the df -h command will have to wait as he is mainly dual booting another os, as that works, indeed that will be the same for the other commands suggested.

I will get back to you withthe results.

All the best from slackbat abd friend.

What is the other os?

Kernel 4.19 is lmde4, kernel 5.10 is lmde5, Assuming the friend is upgrading from lmde4 to lmde5, was "apt dist-upgrade" ran? dist-upgrade in usually ran on a pure debian distro when updating to a newer version, not sure what it will do on lmde.
