Hi, after going through some troubles during the upgrade process from NC 25.0.3, probably partially caused by a defect sdcard, to NC26.0.1 i have now managed to do a fresh install of Nextcloud on a new card and restore my last Backup of NC 25.0.3 and then update it to NC 26.0.1 i have now a working instance except that cron.php is not working. I have read that i need to reinstall PHP and indeed i have now PHP 8.1 and 8.2 on the system. I would like to clean remove PHP and reinstall the version that comes with the latest NCP image. Any hint on how to do this? And what needs to be brought to the PHP NPM folder zo make Nextcloud run again? ---

If cron is failing, but Nextcloud is otherwise operating, than it’ s probably not because of your PHP version. If you’re already upgraded to NC26 than you’re already using at least PHP 8.0 (v8.1 I believe if you’re using `ncp-update-nc`). If you’re running NCP, you should be able to use NCP’s built in update process and not need to mess with upgrading PHP at all on your own unless something gets really messed up. > [@Staying up to date](https://help.nextcloud.com/t/staying-up-to-date/126259): > > It is wise to keep your NCP instance up to date. We’ll explore the update options available from either: ncp-web on port :4443 ncp-config from the command line (cli) / Terminal-UI (TUI). Keep in mind that there are 4 separate parts of NextcloudPi that need updates; Debian (or Raspbian, etc.) - unattended-upgrades NextCloudPi - nc-update-ncp Nextcloud - nc-update-nc Appstore Apps - nc-update-nc-apps What needs updating? Debian Nextcloud NextcloudPi Appstore Apps R… How did you do the NC26 upgrade? ---

Hi, i had done a fresh install of ncp updated ncp, enabled automount, moved the data dir and db dir to the USBdrive then restored my backup, which took way longer than normal, but this might be related to the slower sdcard. After that i did update nc, which also took ages. After that the ncp status page tells me Nextcloud and hpb swrvice is in an error state and my cron.php is obviously not running because news does not get updates. If i try to run cron php manually i see this: ```auto Last login: Mon Jul 3 17:02:22 2023 from 10.0.0.154 Wi-Fi is currently blocked by rfkill.
