So some guy posts a pull request. I, in trying to follow PETSc-rules, want to check out his branch and then merge that rather than use the merge directly from the bitbucket website. So I go to the branch in the bitbucket website and bitbucket claims I can look at it with git fetch && git checkout ianwilliamson/fix-matlab-write-bin-complex (see attachment). I try that and of course it does not work: $ git fetch && git checkout ianwilliamson/fix-matlab-write-bin-complex remote: Counting objects: 56, done. remote: Compressing objects: 100% (56/56), done. remote: Total 56 (delta 48), reused 0 (delta 0) Unpacking objects: 100% (56/56), done. From bitbucket.org:petsc/petsc f685883..cf8fc5e master -> origin/master 7cadcfe..39ea070 knepley/fix-plex-orient -> origin/knepley/fix-plex-orient 565f831..ce993ff knepley/pylith -> origin/knepley/pylith + 3f11d05...21345e8 mlange/refactor-plex-distribute -> origin/mlange/refactor-plex-distribute (forced update) e9d5acc..916966e next -> origin/next error: pathspec 'ianwilliamson/fix-matlab-write-bin-complex' did not match any file(s) known to git. So is bitbucket lying to me or am I doing something wrong. Should this be a feature request to bitbucket ? Remember I am living in the world where I cannot remember how to do anything and thus expect my tools to tell me how to do something. So why cannot bitbucket tell me the truth of how to get this branch? Barry
