Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue. What did you do before the bug happened? (Steps to reproduce your issue) I added an SSH key to Git using a guide from GitHub (https://docs.github.com/en/authentication/managing-commit-signature-verification/telling-git-about-your-signing-key#telling-git-about-your-ssh-key) What did you expect to happen? (Expected behavior) It would sign my commits. What happened instead? (Actual behavior) It throws an error: error: Load key "blah blah blah" invalid format? fatal: failed to write commit object What's different between what you expected and what actually happened? Commits should work, not fail.
