[galaxy-dev] Galaxy Update Problem

Hi all, I installed my Galaxy instance from https://bitbucket.org/galaxy/galaxy-dist/. But I did not use Mercurial to install Galaxy at that time, because I was not farmiliar with Mercurial and failed severed times. The instance imported many tool kits later, as it would be very difficult to restart everthing for me. I tried to use hg command: hg clone https://bitbucket.org/galaxy/galaxy-dist/ cd galaxy-dist hg update stable to make a new copy and copied the ".hg" directory to the former instance and used the "hg update stable" command. Then it reports that there were not files to change. I wonder if there could be any way to update the instance. Thanks, Zhaozhen
