I'm trying desperately to follow the instructions on https://ghc.haskell.org/trac/ghc/wiki/WorkingConventions/Git/Submodules for how to update haddock to follow a small change to GHC. I've checked out the haddock master, made my patch, and want to push to haddock. But my push is rejected for an inscrutable reason: git status # On branch master # Your branch is ahead of 'origin/master' by 1 commit. # nothing to commit (working directory clean) simonpj@cam-05-unx:~/code/HEAD-2/utils/haddock$ git push Counting objects: 9, done.

[remote rejected] HEAD -> master (hook declined) error: failed to push some refs to 'ssh://git@ghc.haskell.org/haddock.git' simonpj@cam-05-unx:~/code/HEAD-2/utils/haddock$ What do I do now? Presumably once that's done I include the change to utils/haddock in my patch to HEAD, correct? Getting to Haddock HEAD added 12 new patches on the haddock branch so I suppose they'll be included too. I don't know whether that is good or bad. help! Simon
