New icinga install on ubuntu 20.04: many PHP Deprecated errors

djnoah · February 13, 2022, 7:41am

This is an entirely new icinga2 and icinga web 2 installation. I am installing icinga web 2 and running into a bunch of PHP Deprecated errors

Here are the installation steps I am using - I am at “Step 6: Install and setup Icinga Web 2”

I am running PHP 8.1.2 (cli) (built: Jan 24 2022 10:42:33) (NTS) [more details below]

Any assistance is appreciated.

Thanks, Lee.

I am hoping to install just PHP 8.0 components.

How do I get this apt command to install PHP 8.0 packages instead of PHP 8.1 packages?

It would be helpful to format your posts for more readability. I personally don’t have as much Ubuntu experience, but it seems like a general Ubuntu question (I’m sure others here may be able to help).
