Plesk on Lightsail Kernelcare Issue – /usr/bin/kcarectl –auto-update spam

I was receiving emails titled “Cron <[email protected]> /usr/bin/kcarectl –auto-update” with a body “The IP 1.2.3.4 was already used for a trial license on 2018-12-23”

At one point, I was receiving one of these per VM every four hours

As I’ve not got a licence anyway, this is easily solved with:

sudo apt-get remove kernelcare
