Fetching all references
Could not fetch special ref '9053ebe6eeb2ae762655b982e27c341cb568366d'; assuming it is not special.
warning: refname '9053ebe6eeb2ae762655b982e27c341cb568366d' 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"
