Have you created a minimal reproduction repository?

Please read the minimal reproductions documentation to learn how to make a good minimal reproduction repository.

• I have provided a minimal reproduction repository
• I don't have time for that, but it happens in a public repository I have linked to: https://github.com/cenk1cenk2/nestjs-tools
• I don't have time for that, and cannot share my private repository
• The nature of this bug means it's impossible to reproduce publicly

Additional context

I'm seeing this happen hundreds of times in the app.

[rarkins]

The error message during git fetch is Error: fatal: couldn't find remote ref refs/heads/origin/renovate/all-dev however we see the message No local branch to delete twice. I can't reproduce locally.
