[HowTo] Install the latest Linux Kernel

[cpedretti]

The Linux Kernel history => https://en.wikipedia.org/wiki/Linux_kernel

The Linux Kernel's => https://www.kernel.org/


To know how kernel are installed:

Code: Select all

uname -a

Good news LMDE4 already has backports repository activated by default, we use later the backports sources to update our kernel.


To search a newest kernel:

Code: Select all

sudo apt search linux-image

In the output we will see a lot of kernels, but we have interest to the latest, at this time the kernel 5.7:




Lets do it and install the latest kernel:

Code: Select all

sudo apt install linux-image-5.7.0-0.bpo.2-amd64 linux-headers-5.7.0-0.bpo.2-amd64 -t buster-backports -y

A reboot is needed to boot on the new kernel:

Code: Select all

sudo reboot

We can check now:

Code: Select all

uname -a

let's take it a step further by removing the old kernels, in general it is advisable to keep 2 kernels in case there is a problem with one of them.

To view the installed kernel:

Code: Select all

sudo dpkg --list 'linux-image*'

In the output you will see how kernel you can purge.


Example to purge a kernel:

Code: Select all

sudo apt autoremove --purge linux-image-5.6.0-0.bpo.2-amd64 linux-headers-5.6.0-0.bpo.2-amd64 -y

We need to upgrade the grub with the changes we made:

Code: Select all

sudo update-grub2

After an reboot in the boot menu, select advanced options, you can also check the kernels who are usable.


In case if you have a graphic card using open firmwares you'll need to update your kernel with it, just check this tutorial

I'd propose to use the respective meta-package instead : apt install linux-image-amd64 -y

Backports are all ready enabled on LMDE4, for optain a update of your kernel make :

Code: Select all

apt update && apt install -t buster-backports linux-image-amd64 -y && apt install -t buster-backports linux-headers-amd64 -y && apt install -t buster-backports firmware-linux firmware-linux-nonfree -y && reboot

Thanks! It worked perfectly. I removed the SSD from the Intel i5-8500 and put it in the 3400G machine after getting the 5.4 kernel. Presto! Picasso drivers installed and working perfectly. Much appreciated!

this method covers backport metapackages and will deliver kernel 5.7 bpo2 currently. If you do want a specific branch, say kernel 5.4 now then search what kernel and kmod packages are already installed and apply the equivalents for the newest bpo package for that branch as per the longer instructions above.

I would recommend using the bpo linux firmware packages too though.

About backports

You are running Debian stable because you prefer the stable Debian tree. It runs great, there is just one problem: The software is a little bit outdated compared to other distributions. That is where backports come in.

Backports are recompiled packages from testing (mostly) and unstable (in a few cases only, e.g. security updates) in a stable environment so that they will run without new libraries (whenever it is possible) on a Debian stable distribution

Backports cannot be tested as extensively as Debian stable, and backports are provided on an as-is basis, with risk of incompatibilities with other components in Debian stable. Use with care!

It is therefore recommended to select single backported packages that fit your needs, and not use all available backports.

the latest stable linux kernel is available => 5.9

To update it just follow the HowTo up there.

Why bother...kernel 5.9 reached EOL, (End of Life), Dec.22nd 2020...DAMIEN

Thanks for the info, but for the moment the 5.10 kernel is not yet available, see attached screenshot.




Here we can see on the https://www.kernel.org/ Site that the 5.10.4 are the latest stable availlable, but in my example we are working on LMDE not Mint, I think that's why the latest kernel is not yet offered.

You will have to wait while waiting for the last stable kernel to be made available on LMDE.

I have LMDE4. I installed the proprietary nvidia drivers on the 4.19 default kernel. if I install a new kernel from backports, I update grub, but then at the boot screen, I select to boot the new kernel, but after giving Enter, I am left with a black screen. instead if I start from 4.19 everything works fine. so the problem is the nvidia driver. is there an easier way than having to remove the nvidia drivers, install the new kernel, and then reinstall the nvidia drivers on the new kernel again?

excuse me for the late reply, it is possible that the driver was not activated during the installation of the new kernel.

To remedy this, simply reinstall the following packages in recovery mode:

Code: Select all

sudo apt install -t buster-backports nvidia-driver nvidia detect firmware-misc-nonfree -y

Hope this can solve your issue.

i'll try, but in recovery mode this is what it happens:
https://ibb.co/dbL7Ssq
https://ibb.co/R3QNrCc

i have install the 5.10 kernel amd64 backport, and the relative headers.

what i have to do?
thanks!

In the recovery mode unlock the root account with your password then try to reinstall the driver like:

Code: Select all

sudo apt install --reinstall -t buster-backports nvidia-driver nvidia detect firmware-misc-nonfree -y

Hello,
1) About your signature, if you use liquorix kernels, you must know they are not fully supported and may cause random issues.
2) The standard procedure to install nvidia in Debian (which LMDE4 is more or less) can be found here :
https://wiki.debian.org/NvidiaGraphicsDrivers
3) However, the link to it comes from :
https://wiki.debian.org/DontBreakDebian ... ll_scripts
which states :

Debian includes free and open-source drivers that support most video cards. The free drivers provide the best integration with the rest of the Debian system and work quite well for most users.

This is plain logic because each kernel contains its own nouveau driver. So, unless you absolutely need some feature the nouveau driver doesn't provide, keep it.

[ne0h]

I solved.
fresh installation of LMDE4 without nvidia driver. then i installed the 5.10 kernel, then i installed the nvidia drivers manually on this kernel. everything OK!

The latest stable linux kernel is available => 5.10.0-0.bpo.9

To update it just follow the HowTo up there.

[cpedretti]

The latest stable linux kernel for LMDE5 is available => 5.15.0-0.bpo.3

To update it just follow the HowTo up there (don't forget to change the old backports with bullseye-backports.)

[cpedretti]

The latest stable linux kernel for LMDE5 is available => 5.16.0-0.bpo.4

To update it just follow the HowTo up there (don't forget to change the old backports with bullseye-backports.)

[xenopeek]

Why are you not using command like:
apt install -t bullseye-backports linux-image-amd64 linux-headers-amd64
That pulls in the current backports kernel version, not needing to specify version.

[antikythera]

Backports are all ready enabled on LMDE4, for optain a update of your kernel make :

Code: Select all

apt update && apt install -t buster-backports linux-image-amd64 -y && apt install -t buster-backports linux-headers-amd64 -y && apt install -t buster-backports firmware-linux firmware-linux-nonfree -y && reboot

Thanks! It worked perfectly. I removed the SSD from the Intel i5-8500 and put it in the 3400G machine after getting the 5.4 kernel. Presto! Picasso drivers installed and working perfectly. Much appreciated!

this method covers backport metapackages and will deliver kernel 5.7 bpo2 currently. If you do want a specific branch, say kernel 5.4 now then search what kernel and kmod packages are already installed and apply the equivalents for the newest bpo package for that branch as per the longer instructions above.

I would recommend using the bpo linux firmware packages too though.

still works for LMDE5, just "replace all" buster with bullseye

Code: Select all

apt update && apt install -t bullseye-backports linux-image-amd64 -y && apt install -t bullseye-backports linux-headers-amd64 -y && apt install -t bullseye-backports firmware-linux firmware-linux-nonfree -y && reboot

I prefer to use the absolute path, just to have control over the interpretation and not the system's choice.

But it's always useful to know the relative paths.

Code: Select all

apt update && apt install -t buster-backports linux-image-amd64 -y && apt install -t buster-backports linux-headers-amd64 -y && apt install -t buster-backports firmware-linux firmware-linux-nonfree -y && reboot

You forgot to mention that you were using the console as root user
