在尝试使用capistrano部署网站时，我收到以下消息：

Please make sure you have the correct access rights
and the repository exists.
然而，当我手动运行此命令时，作为同一个用户，一切正常：
$ export GIT_ASKPASS="/bin/echo" GIT_SSH="/tmp/git-ssh-mysite-staging-username.sh" ; /usr/bin/env git ls-remote --heads git@bitbucket.org:username/mysite.git

我已经验证我的公钥是存储库的bitbucket部署密钥。这之前工作得很好。有什么方法可以进一步调试吗？
答案 0 :(得分：0)
我找到了解决方案here。显然<?xml version="1.0" encoding="UTF-8" ?>
