Hello everybody, i'm a sysadmin in charge of installing a Galaxy server. I'm a totally beginner regarding this software. I've installed Galaxy using the documentation on the wiki (with Apache as a proxy and postgresql as database) and everything went fine. I've tried to create a new library as a galaxy admin. I've added a dataset using "Upload files from filesystem paths" without copying data into galaxy. To test the behaviour of Galaxy in a weird situation i've added "/" (:D), clicked on "Upload to library" and closed the navigation tab after one minute. As a result, the new data library appears under the "Manage data libraries" page. But, when i click on it, i've got a server error. Here is the traceback : -------------------------- .... File '/home/galaxy/galaxy-dist/database/compiled_templates/library/common/browse_library.mako.py', line 229 in render_render_content if not trans.app.security_agent.library_is_public( library, contents=True ): File '/home/sis/jbdenis/galaxy-dist/lib/galaxy/security/__init__.py', line 541 in library_is_public File '/home/sis/jbdenis/galaxy-dist/lib/galaxy/security/__init__.py', line 559 in folder_is_public File '/home/sis/jbdenis/galaxy-dist/lib/galaxy/security/__init__.py', line 559 in folder_is_public File '/home/sis/jbdenis/galaxy-dist/lib/galaxy/security/__init__.py', line 559 in folder_is_public File '/home/sis/jbdenis/galaxy-dist/lib/galaxy/security/__init__.py', line 562 in folder_is_public AttributeError: 'NoneType' object has no attribute 'dataset' -------------------------- My question is : how can i delete this library without messing with the database consistency? Any hints ?
