Issue description

I have a UDM PRO with UniFi OS 1.12.30 (which is not in the compatibility list).
First question, do I have to use a different package?

I have extracted the package to both locations (/data and /mnt/data) to make sure that's not the source of the problem. According to the docs I should extract the code to /mnt/data but this specific folder did not exist, I also tried to create the path manually.

When running the setup script I receive the following error:
Unsupported Kernel version 4.19.152-al-linux-v10.2.0-v1.12.30.4325-060f0fe

Configuration and log output

root@ubnt:/# ./mnt/data/wireguard/setup_wireguard.sh

Hello @jpl-ivengi,

So 1.12.30 has a built-in wireguard module, which should be loaded by this script. However, I see that it says the modprobe command was not found, which is very weird.

In any case, since the module is built-in, it should automatically get loaded by wireguard. You can try to simply proceed with the wireguard configuration and starting it with wg-quick to see if it works or if it has any issues loading the module.

Please try that and tell me how it goes. Thank!
