Github - Merging is blocked - The base branch requires all commits to be signed

Question

Github is blocking the pull request from being merged, even though all the commits are verified.
Rule settings: 'Require signed commits' & 'Include administrators' are checked.
Does anyone know how to solve this?

Answer 1

It seems like this is a GitHub web interface only glitch.

The system can verify the signatures internally.

The trick to get through this is to use the "Command line instructions".

I was able to merge the branch without turning off any checks.
