cannot [re]install Wireguard

Troubleshooting
1

For whatever reason I cannot [re]install wireguard, I suppose that happened after the kernel upgrade.
I see some errors below but not sure how to fix them, please advise.
BTW, is it possible to install a newer version of wireguard with this kernel?

Did you checked the log file? /var/lib/dkms/wireguard/0.0.20190123/build/make.log
Can you share some more details on your device and DietPi version! Did you tried to reboot after the kernel update?

found something similar to your issue https://www.reddit.com/r/WireGuard/comments/ho9pnr/20200623_of_wireguarddkms_build_error_on_ubuntu/

Not sure if this is something you like to try

Btw: did you run apt update && apt upgrade to have all packages updated?

Thank you for looking into this issue. Yes, I’ve performed all the traditional passes including reboot/update/upgrade/etc.
Finally I just downloaded

https://git.zx2c4.com/wireguard-linux-compat/snapshot/wireguard-linux-compat-1.0.20210606.zip

and then built it manually without dkms.
