RPi 4B kernel header mismatch

[rico15]

Hello - I'm new to this forum and fairly new to linux.

I have a mismatch between the kernel on my RPi4 and the latest repository version and cannot find instructions on how to resolve this.

I am asking this question in the context of a package/distro which I don't have control over, so am tracking their releases. I want to add some packages which are [currently] outside their release. One such package requires the headers.

I cannot find in the RPi Documentation, or do not understand, how either to update the kernel for a non RaspberryOS distro, or to load the headers for linux 6.6.36-1-rpi.

I have looked at themake_clickable_callback(MAGIC_URL_FULL, ' ', 'http://alaa.ad24.cz/', '', ' class="postlink"') archive but unfortunately the headers for 6.6.36-1-rpi are missing. So I think my only option is to upgrade the kernel, but I can't find out how on the RPi. I'm aware it lives on /boot, but need the instructions how to get it there.

For the moment I have not done pacman -Syu (i) because the headers are not installed anyway and (ii) in case it makes things worse.

Can anybody help?

And a bonus would be how to keep kernel and headers aligned via DKMS in the future, if possible.

Arch (and Arch ARM) are rolling release distros. As such, repos update as new packages are built/available which is at a rapid pace. You should never install new packages (headers in your case) without updating your system to be in sync with contemporary packages. This situation is termed a "partial update" which is not supported.
make_clickable_callback(MAGIC_URL_FULL, '
', 'https://wiki.archlinux.org/title/System_maintenance#Partial_upgrades_are_unsupported', '', ' class="postlink"')

Long story short, first update:
pacman -Syu

then install new packages:
pacman -S foo bar

OK well I was not completely surprised by that answer. At least it narrows my list of questions to one:

How do I upgrade the kernel to the version required by the latest packages ie

6.6.36-1-rpi > 6.6.40-1

as required for the latest headers?

@graysky - tks for the link, but I can already upgrade packages. I can't (OP) upgrade the kernel to match the latest packages. This is on the RPi4.

How to upgrade the kernel to 6.6.36-rpi?

Sorry - misspoke. Kernel is currently 6.6.36, upgrade required to 6.6.40-1[rpi?]

Further browsing in the Forum reveals this :
make_clickable_callback(MAGIC_URL_LOCAL, '

Where are the instructions referred to please?
