Validation seems to not show any errors.
I recently upgraded from 18.04 to 20.04, as validate reported PHP 7.2 being “EOL” for libreNMS. So figured, hey, let’s get ahead of this.
Initially, didn’t notice it, but I have confirmed my libreNMS setup is not E-Mailing stuff. So, I suspect I’m missing a PHP package or something. I’m really not sure what to be checking in an upgrade like this. I went from Ubuntu 18.04 to 20.04. And from PHP 7.2 to 7.4.
