I'm using git revert 028cf1f -m1 1
(following this answer)
It yields the result:
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean
I'm trying to undo this commit:
commit 028cf1f4969333a0e547a8ddbcd21d9647bb05c3
Merge: b1c0783 fa38861
The commit has already been pushed, if that's relevant to what I'm seeing.
