[galaxy-dev] Update Galaxy instance with Mercurial error

Dear Galaxy users, I am running a Galaxy instance in my institution's server and I want to keep it up to date with the latest release. Nevertheless when i try hg incoming i get the following error: abort: There is no Mercurial repository here (.hg not found)! Most probably the administrator of the server has downloaded the Galaxy-dist directory without the use of Mercurial (I was suspicious of that all along as the directory of the Galaxy installation is named galaxy_dist and not galaxy-dist). Is there another way to update my instance? Thank you, Makis Ladoukakis
