WordPress – PHP Fatal error: Uncaught Kohana_Cache_Exception [ 0 ]: PHP APC extension is not available

after a migration from ubuntu 18;04 to 20.04, my php site comes up with an error in the apache logs

 [Tue Apr 23 23:09:52.521788 2024] [:error] [pid 4026] [client 10.164.136.69:39608] PHP Fatal error:  Uncaught Kohana_Cache_Exception [ 0 ]: PHP APC extension is not available. ~ MODPATH/cache/classes/kohana/cache/apc.php [ 52 ]n  thrown in /var/www/*/cache/apc.php on line 52

when I check in the file at line 52, this is what I get

 48         protected function __construct(array $config)
 49         {
 50                 if ( ! extension_loaded('apc'))
 51                 {
 52                         throw new Kohana_Cache_Exception('PHP APC extension is not available.');
 53                 }
 54
 55                 parent::__construct($config);
 56         }

any idea where the problem might be coming from?

by default the site was on php 5.6, after migration to ubuntu 20.04, php 7 was installed by default, I ran commands to switch php 7.4 to 5.6 but no change
