Hi, I run upgrade: hg pull -u -r 40f1816d6857 on our local instance, and I'm now unable to start Galaxy.. Here is the content of Galaxy_log: Traceback (most recent call last): File "<galaxy_dir>/galaxy-dist/lib/galaxy/web/buildapp.py", line 81, in app_factory from galaxy.app import UniverseApplication File "<galaxy_dir>/galaxy-dist/lib/galaxy/app.py", line 11, in <module> from galaxy.objectstore import build_object_store_from_config File "<galaxy_dir>/galaxy-dist/lib/galaxy/objectstore/__init__.py", line 27, in <module> from galaxy.objectstore.s3_multipart_upload import multipart_upload File "<galaxy_dir>/galaxy-dist/lib/galaxy/objectstore/s3_multipart_upload.py", line 22, in <module> eggs.require('boto') File "<galaxy_dir>/galaxy-dist/lib/galaxy/eggs/__init__.py", line 415, in require raise EggNotFetchable( str( [ egg.name for egg in e.eggs ] ) ) EggNotFetchable: ['boto'] Removing PID file <galaxy_dir>/galaxy-dist/galaxy.pid Is that an error specific to our instance? Is there a way to downgrade Galaxy? Thanks by advance for your answer..
