Hello all, We just ran into a Tool Shed installation problem under a test installation of Galaxy v16.01, while trying to install the meme_fimo tool. Clicking through the GUI takes me to the failed install of the perl_xml_parser_expat version 2.41 package (under package_perl_xml_parser_expat_2_41), https://toolshed.g2.bx.psu.edu/view/iuc/package_perl_xml_parser_expat_2_41vi... https://github.com/galaxyproject/tools-iuc/blob/master/packages/package_perl... The Admin GUI shows this long stack trace error: File "/mnt/qnap/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/install_manager.py", line 123, in install_and_build_package_via_fabric tool_dependency = self.install_and_build_package( install_environment, tool_dependency, actions_dict ) File "/mnt/qnap/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/install_manager.py", line 81, in install_and_build_package initial_download=True ) File "/mnt/qnap/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/tool_dependencies/recipe/recipe_manager.py", line 31, in execute_step initial_download=initial_download ) File "/mnt/qnap/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/tool_dependencies/recipe/step_handler.py", line 1253, in execute_step job_name=package_name) File "/mnt/qnap/galaxy/galaxy-dist/lib/tool_shed/galaxy_install/tool_dependencies/recipe/install_environment.py", line 140, in handle_command error_message=error_message) File "/mnt/qnap/galaxy/galaxy-dist/lib/tool_shed/util/tool_dependency_util.py", line 390, in set_tool_dependency_attributes sa_session.flush() File "/mnt/shared/galaxy/galaxy-dist/.venv/lib/python2.7/site-packages/sqlalchemy/orm/scoping.py", line 150, in do return getattr(self.registry(), name)(*args, **kwargs) ...

We also have e2 80 99 which is the matching right single quote. While I can go over the full INSTALLATION.log to work out what might be wrong, there is clearly a Galaxy problem with the UTF-8 encoded character. Going over the Galaxy mailing list there have been similar problems (although not ToolShed related) reported in the past (2013) with MySQL and the table encodings: http://dev.list.galaxyproject.org/error-with-unicode-output-td4662783.html Are there still known issues with encodings and the MySQL galaxy schema? Are we likely to run into other corner cases with MySQL where we would be better off switching to PostgreSQL? Regards, Peter
