Also check if you have security enabled in your sources.list. Some read: https://www.devuan.org/os/packages

I have several installations of Devuan Chimaera.  I run regular updates, always for standard Devuan repositories.
I notice that the systems never upgraded beyond 11.1 (reading the /etc/debian_version). I also noticed discrepancies between the installed running linux image and headers, which is now causing issues with building a driver for a USB Wifi dongle.
Machine 1:
Updated 14/2/2024
Image: 5.10.0.26-amd64
Headers: 50.10.0-26
Debian version: 11.1

Machine 2 (Virutal):
Updated 15/2/2024
Image: 5.10.0.9-amd64
Headers: 5.10.9-adm64
Debian-version 11.1

Machine 3:
Updated 14/2/2024
Image: 5.10.0.9-amd64
Headers: 5.10.0.28-amd64 (possibly installed by get dkms - really not sure) build script looking for 5.10.0.9-amd64

Tried apt-get update -> upgrade and dist-upgrade.  No change.
I would have thought all systems would be running 5.10.0.28 at least? and linking to the same headers as the image.
What am I doing wrong here?
