I think I have a very similar issue. Unable to get Wireguard running on an odroid hc2.
Trying to install wireguard-dkms yields to the following output (After pinning debian 11 debs):
user@device:~$ sudo apt install wireguard-dkms --reinstall

Building for 5.4.243-odroidxu4 6.1.0-10-rt-armmp
Module build for kernel 5.4.243-odroidxu4 was skipped since the
kernel headers for this kernel do not seem to be installed.
Module build for kernel 6.1.0-10-rt-armmp was skipped since the
kernel headers for this kernel do not seem to be installed.
The reason why it is unable to build the module seems to be a mismatch between the linux image and linux headers:

user@device:~$ uname -a

Any idea how to fix this?
