The update was unsuccessful. Please report this issue to the ownCloud community.
For an unknown reason, the upgrade using the automated method using the browser didn’t worked out as expected (it always did for me in the past). To workaround this issue, you may run the update manually instead.
1. You need first to make sure that APC is enabled for php-cli. To enable it, either edit “apcu.ini” or append the following to PHP config file :
/etc/php5/cli/php.ini
Append (or enable) this parameter :
apc.enable_cli=1
2. Login as the user that the Web server run for your ownCloud installation.
su - www-data
NOTE : Web server setup are variables, you may need to temporary change the user shell from “nologin” to “bash”.
3. Browse to your ownCloud installation (default location is /var/www/owncloud/) and run the following command :
./occ upgrade
Output example :
www-data@cloud:~/owncloud$ ./occ upgrade
ownCloud or one of the apps require upgrade – only a limited number of commands are available
Set log level to debug – current level: ‘Warning’
