An unhandled exception has been thrown:
OCP\HintException: [0]: Memcache \OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)
origin server details : Ubuntu 20.04.6 - PHP 8.0.13
new server details: Ubuntu 22.04 - PHP 8.1.2
been searching forums looking for solution, unable to replicate, any help to determine how to fix the problem appreciated
apt search php | grep -i oc or maybe greb for mem. One php module is missing from your system. It could also be that you may have not migrated the apache folders correctly or in their entirety, although less likely.
