key_load_public: неверный формат с помощью scp или git clone на Ubuntu 15.10

После новой установки Ubuntu 15.10 при использовании scp или git clone я получаю следующее предупреждение (сама команда не прерывается): key_load_public: invalid format

Как я могу получить

Обновление: это результат работы scp -vvv:
