I don’t think its recommended to create just another thread of the very same question: Cannot install because of error - check it here . Its way better to show some minimal effort like i did by using a search like Search results for 'calendarsubscriptions' - ownCloud Central to find threads like CentOS 6 upgrade to OC 10.0.3 failed or Owncloud installation / setting up the admin account doesnt work leading to some information that this should work again with oC 10.0.4
