Hello,

When updating local instance of our Galaxy, the hg aborted: pulling from https://bitbucket.org/galaxy/galaxy-dist/ searching for changes adding changesets adding manifests adding file changes added 1482 changesets with 3989 changes to 1340 files abort: untracked file in working directory differs from file in requested revision: 'doc/Makefile'

and : -bash-3.2$ hg update abort: untracked file in working directory differs from file in requested revision: 'doc/source/conf.py'

Could you please tell me what this may be the problem?

Thanks
