Integrity check fails due to missing signature.json

[taddeus]

Using the latest (9.0) image, the installation works but there is an error in the admin section saying that some files have not passed the integrity check. This is because owncloud introduced code signing which requires signature.json files in all app directories and in the "core" directory. I downloaded the 9.0.0 apps from the owcloud website, which fixed the error for the apps, but the check for the core directory still fails. I tried inserting core/signature.json from owncloud-9.0.0.tar.bz2 into the container but the versions seem to mismatch, since the hashes are incorrect according to the integrity check.
