I'm trying to update my kernel following the instructions Updated 27 Apr 2022.

At the point 3 I get the error that flash-kernel is not installed:

root@debian:/boot# apt-get remove flash-kernel
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package 'flash-kernel' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

what am I doing wrong ?

I believe you can safely ignore this package removal step.

Thank you. I supposed it was like that but I wanted to be sure.

Everything went smooth.

In the boot folder now I have a mess of files:

 config-5.17.4-kirkwood-tld-1               linux-5.17.4-kirkwood-tld-1.patch                  uEnv.txt                       zImage-5.13.6-kirkwood-tld-1
..                                dts                                        linux-dtb-5.17.4-kirkwood-tld-1.tar                uImage                         zImage-5.17.4-kirkwood-tld-1
System.map-5.13.6-kirkwood-tld-1  initrd.img-5.13.6-kirkwood-tld-1           linux-headers-5.13.6-kirkwood-tld-1_1.0_armel.deb  uInitrd
System.map-5.17.4-kirkwood-tld-1  initrd.img-5.17.4-kirkwood-tld-1           linux-headers-5.17.4-kirkwood-tld-1_1.0_armel.deb  vmlinuz-5.13.6-kirkwood-tld-1
config-5.13.6-kirkwood-tld-1      linux-5.17.4-kirkwood-tld-1-bodhi.tar.bz2  linux-image-5.17.4-kirkwood-tld-1_1.0_armel.deb    vmlinuz-5.17.4-kirkwood-tld-1

I guess I can delete the followings:

zImage-5.13.6-kirkwood-tld-1
linux-dtb-5.17.4-kirkwood-tld-1.tar
System.map-5.13.6-kirkwood-tld-1
initrd.img-5.13.6-kirkwood-tld-1
linux-headers-5.13.6-kirkwood-tld-1_1.0_armel.deb
linux-headers-5.17.4-kirkwood-tld-1_1.0_armel.deb
vmlinuz-5.13.6-kirkwood-tld-1
config-5.13.6-kirkwood-tld-1
linux-5.17.4-kirkwood-tld-1-bodhi.tar.bz2
linux-image-5.17.4-kirkwood-tld-1_1.0_armel.deb

right ?

all the ones referring to 5.13.6

Yes, instruction to remove is there as a precaution when people install the kernel from a mainline rootfs.

delete:

> linux-dtb-5.17.4-kirkwood-tld-1.tar
> linux-5.17.4-kirkwood-tld-1-bodhi.tar.bz2

But keep everything else, those are kernel files, in case you have to recreate the uImage and uInitrd. And also in case you have to reinstall the current kernel or previous kernel.

You coud uninstall the kernel 5.13.6 to save space and clean up. But I would keep that as a back up kernel (so you can boot back to that kernel too).

Do a listing with this command so sort files by date in reverse, so that you can see it is not a mess afterall:

ls -lart

You could also create a folder and move them there

cd /boot
mkdir -p kernel
mv -i linux-image-*.deb *.tar *.bz2 ./kernel

Why not. the point here is that at every kernel update the mess inceases :)

Yup :) But the kernel files must be in /boot for certain things to work, such as Debian version upgrade. So keep 2 versions and uninstall the rest.

Example to uninstall a kernel version (any version except the one running).

List them

root@tldDebian:/boot# dpkg -l | grep linux-image
ii  linux-image-5.14.9-mvebu-tld-1:armhf   1.0                                 armhf        Linux kernel, version 5.14.9-mvebu-tld-1
ii  linux-image-5.15.5-mvebu-tld-1:armhf   1.0                                 armhf        Linux kernel, version 5.15.5-mvebu-tld-1
ii  linux-image-5.16.5-mvebu-tld-1:armhf   1.0                                 armhf        Linux kernel, version 5.16.5-mvebu-tld-1
ii  linux-image-5.17.4-mvebu-tld-1:armhf   1.0                                 armhf        Linux kernel, version 5.17.4-mvebu-tld-1

Uninstall 5.14.9-mvebu-tld-1

dpkg --purge linux-image-5.14.9-mvebu-tld-1
