Hello I don't understand why git pull --rebase --recurse-submodules fails after a git reset --hard to the previous commit. I didn't touch the submodule, it's supposed to be clean: $ git clone --recursive git@xxxxxxxxxx:open-mpi/ompi.git [...] $ git reset --hard HEAD^ HEAD is now at 395e2c9d8f Merge pull request #7364 from awlauria/fix_compile $ git pull --rebase --recurse-submodules Fetching submodule opal/mca/hwloc/hwloc2/hwloc fatal: cannot rebase with locally recorded submodule modifications Why is failing here? $ git submodule status 38433c0f5fae0b761bd20e7b928c77f3ff2e76dc opal/mca/hwloc/hwloc2/hwloc (hwloc-2.1.0rc2-33-g38433c0f) (that's expected) $ git status HEAD detached at 38433c0f nothing to commit, working tree clean Thanks Brice
