Unable to push to GITLAB after cleaning

[BishopWolf]

Basically after cleaning gitlab says

remote: GitLab: You cannot push commits for '[email protected]'. You can only push commits that were committed with one of your own verified emails.

Is there a way to handle this? I want to keep contributor history

@BishopWolf It seems bfg rewrote commits that were authored by '[email protected]', and now you need their gpg key to push their rewritten commits. Your best bet is to change the author of all those commits to a dummy author, I venture. I don't know how you can do that, websearch it.
