>>> squashfs e38956b92f738518c29734399629e7cdb33072d3 Downloading Fetching all references Could not fetch special ref 'e38956b92f738518c29734399629e7cdb33072d3'; assuming it is not special. warning: refname 'e38956b92f738518c29734399629e7cdb33072d3' 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.
