Problem in upgrading OJS 3 into OJS 3.0.1

Software Support

Dear @asmecher

In fact I didn’t make a backup from my database but I turned on the debug and tried again to upgrade the last line was:

1062: ALTER TABLE causes auto_increment resequencing, resulting in duplicate entry '906' for key 'PRIMARY'
                                ADOConnection._Execute(ALTER TABLE library_files DROP COLUMN `revision`, false) % line 1051, file: adodb.inc.php
                             ADOConnection.Execute(ALTER TABLE library_files DROP COLUMN `revision`) % line  440, file: Installer.inc.php
                          Installer.executeSQL(ALTER TABLE library_files DROP COLUMN `revision`) % line  435, file: Installer.inc.php
                       Installer.executeSQL(Array[28]) % line  375, file: Installer.inc.php
                    Installer.executeAction(Array[3]) % line  265, file: Installer.inc.php
