git message "load pubkey ... invalid format" after upgrade to Git 2.27

Question

After upgrading to Git 2.27 (on Windows) whenever I execute operations on remote repositories authorized with SSH, Git emits "load pubkey ... invalid format" claiming that the private key file has an invalid format. The operation is executed successfully anyway but message is strange.

Checked file format (UTF) and LF line endings, copied private key file from an unmodified source to .ssh folder. No success.

Answer 1

Found this issue: https://github.com/git-for-windows/git/issues/2743 and copied corresponding .pub file to .ssh folder: works again
