[git] Abort a git cherry-pick?

Try also with '--quit' option, which allows you to abort the current operation and further clear the sequencer state.

--quit Forget about the current operation in progress. Can be used to clear the sequencer state after a failed cherry-pick or revert.

--abort Cancel the operation and return to the pre-sequence state.

use help to see the original doc with more details, $ git help cherry-pick

I would avoid 'git reset --hard HEAD' that is too harsh and you might ended up doing some manual work.
