I tried to upgrade from 22.214.171.124 to 9.0.4, which died midway because of a php timeout, I should have used occ.
So I restored the web folder from 8.2.2, I dont know why, I wasn't thinking clearly. Then did an occ upgrade. This succeeded but the site didn't work. The error I was receiving was Class 'OCA\FederatedFileSharing\AppInfo\Application' not found in /var/www/owncloud/ocs/routes.php on line 102
I deleted the owncloud folder, restored from my 126.96.36.199 backup, then did an occ upgrade. Now I get PHP Fatal error: Call to undefined method OCA\Federation\AppInfo\Application::setupCron() in /var/www/owncloud/apps/federation/appinfo/update.php on line 23 and the upgrade appears to have failed.
Any help would be appreciated.
