无法运行 jhbuild：以其他用户身份执行命令时出错：未经授权

Question

我在跑步

jhbuild sysdeps --install

运行此命令后，它会要求进行身份验证：

==== AUTHENTICATING FOR org.freedesktop.policykit.exec ===
Authentication is needed to run `/usr/bin/apt-get' as the super user
Multiple identities can be used for authentication:

选择一个用户并输入正确的密码后，显示此错误：

Choose identity to authenticate as (1-2): Invalid response `'.
==== AUTHENTICATION CANCELED ===
Error executing command as another user: Not authorized

我曾提到https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1077546也。我无法修复此问题。请提出一些建议。
