You can get rid of the errors by doing
git remote prune <origin>
Where <origin> is the name you have for the upstream repo, normally
'origin'.

error: cannot lock ref 'refs/remotes/origin/wip/hsyl20/dynflags': 'refs/remotes/origin/wip/hsyl20/dynflags/exception' exists; cannot create 'refs/remotes/origin/wip/hsyl20/dynflags'
This one is because I've removed some of my wip branches already merged upstream. Their names were conflicting with a new branch name (wip/hsyl20/dynflags).
I forgot that everyone fetches every /wip branch so now it conflicts for everyone... I need to remember to remove the branch when !5845 will be merged.
Should I worry?
No. The submodule seems to be checked out correctly even with the error.

PS: I still think we shouldn't have that many wip branches in the main repositories (cf https://mail.haskell.org/pipermail/ghc-devs/2019-February/017031.html)
