remote: Handle missing config values when deleting a remote Somehow I ended up with the following in my ~/.gitconfig: [branch "master"] remote = origin merge = master rebase = true I assume something went crazy while I was running the git.git tests some time ago, and that I never noticed until now. This is not a good configuration, but it shouldn't cause problems. But it does. Specifically, if you have this in your config, and you perform the following set of actions: create a remote fetch from that remote create a branch off of the remote master branch called "master" delete the branch delete the remote The remote delete fails with the message "Could not find key 'branch.master.rebase' to delete". This is because it's iterating over the config entries (including the ones in the global config) and believes that there is a master branch which must therefore have these config keys. https://github.com/libgit2/libgit2/issues/3856
