Unable to add my channel after guix pull error, `commit X not signed by an authorized key: Y`

I’ve created my own user repo channel and have gpg keys signed to my commits.
Yet I’m still receiving this error.

What could be the issue?

Solved by deleting git history

git checkout --orphan newBranch
git add -A  # Add all files and commit them
git commit
git branch -D main  # Deletes the main branch
git branch -m main  # Rename the current branch to main
git push -f origin main  # Force push main branch to github
git gc --aggressive --prune=all     # remove the old files
