Can't install?

[garrett85]

Linux Mint 20.1 & PHP 7.4.3

I'm following the installation instructions at https://phalcon.io/en-us/download/linux
But his what I'm getting when I get to the following commands.

sudo apt-get install php7-phalcon
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package php7-phalcon

sudo apt-get install php7.0-phalcon
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package php7.0-phalcon
E: Couldn't find any package by glob 'php7.0-phalcon'
E: Couldn't find any package by regex 'php7.0-phalcon'

Where am I doing wrong here? Thanks.

For anyone else who find this very unhelpful community, I was able to get this installed after running sudo apt install php-psr

For the version you are trying to install PSR is a requirement.
