Я столкнулся с проблемой при попытке клонировать тестовое репо (общедоступное) из битбакета, как показано ниже. Как ни странно, ssh auth не проходит для битбакета и отлично работает для github, когда к обеим учетным записям добавлен один и тот же открытый ключ. Я предполагаю, что существует какая-то разновидность согласования ssh между github и bitbucket, которая не работает с версией opnessh на моем сервере aix 7.1. Есть какие-нибудь подсказки, что здесь можно сделать, чтобы найти первопричину? Обратите внимание, что клон https на битбакете работает нормально.
