Fresh installation of 10.3.1.1 fails with duplicate key

Sending the initial setup webpage fails with:

Error while trying to create admin user: An exception occurred while executing ‘ALTER TABLE oc_persistent_locks ADD CONSTRAINT FK_F0C3D55B93CB796C FOREIGN KEY (file_id) REFERENCES oc_filecache (fileid) ON DELETE CASCADE’: SQLSTATE[23000]: Integrity constraint violation: 1022 Can’t write; duplicate key in table ‘#sql-25b8_412283a

Hey,

maybe you can use the issue template which i’m getting presented when creating a new thread in this “Server” category?

I think others are probably better able to help you if you provide more information about your environment (e.g. operating system, database, database version, specific database configuration).

Package: owncloud-10.3.1.tar.bz2
Host: d)f ManagedHosting Basic (ISP)
PHP: 7.2.11
MySQL: 5.6.19

The database tables are created by the install script, but after a few seconds a failure with the error message mentioned above.
