If you have unsigned commits on a branch, you can re-sign them with your GPG uploaded key. Requires GH CLI, gpg installed.

README.md

The base branch requires all commits to be signed If you need to setup GPG, you can read our helpful guide.

Then once you have:

• gpg installed
• GitHub CLI installed (optional but useful)
• a key generated for your Name and email, in this example: Lantrix [email protected]
• your gpg public key uploaded to GitHub
• You can rebase and re-sign all the commits and force push the branch as a potential solution.
