Linux: Missing linux-headers-4.19.23-v7
I just updated to the new firmware for my 3+ which brings down kernel 4.19.23. I need to rebuild some modules (wireguard) and it fails because headers are missing.
pi@raspberrypi:~ $ sudo apt install linux-headers-$(uname -r)

E: Couldn't find any package by regex 'linux-headers-4.19.23-v7'
pi@raspberrypi:~ $
Help !

4.19 is still in test, so apt will not have been updated to it. Did you rpi-update? We don't really recommend that in general usage.
I'd suggest reverting to an earlier supported kernel.

Yes I did an rpi-update. What is the easiest way to revert to an earlier kernel?
Thanks

I think an apt update apt dist-upgrade will load the latest release kernel

apt install raspberrypi-kernel{,-headers}

Thanks for the suggestions. I found the answer here... https://www.raspberrypi.org/documentation/linux/kernel/updating.md
Given this was me getting ahead of things... should I close out this issue or leave it open?
