Fetching all references
Could not fetch special ref '7524160b29a476f7e87bc14fddf12d349f9a3c5e'; assuming it is not special.
warning: refname '7524160b29a476f7e87bc14fddf12d349f9a3c5e' is ambiguous.
Git normally never creates a ref that ends with 40 hex characters
because it will be ignored when you just specify 40-hex. These refs
may be created by mistake. For example,

  git checkout -b $br $(git rev-parse ...)

where "$br" is somehow empty and a 40-hex ref is created. Please
examine these refs and maybe delete them. Turn this message off by
running "git config advice.objectNameWarning false"
