Как удалить origin / master в Git

Я не могу удалить origin/master С моего сервера. Не знаю почему.

сообщение об ошибке следующее

remote: error: By default, deleting the current branch is denied, because the next
remote: error: 'git clone' won't result in any file checked out, causing confusion.
remote: error: 
remote: error: You can set 'receive.denyDeleteCurrent' configuration variable to
remote: error: 'warn' or 'ignore' in the remote repository to allow deleting the
remote: error: current branch, with or without a warning message.
remote: error: 
remote: error: To squelch this message, you can set it to 'refuse'.
