Apt-get 每次都会给出身份验证警告

每当我 apt-get 某个东西时，它都会警告我它未经身份验证。这是一个新问题；它今天才出现。当我这样做时apt-key update，它什么也不做，并apt-get update在输出的末尾给我这个错误：

W: GPG error: http://archive.canonical.com precise Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <[email protected]>

有人知道发生了什么或如何解决它吗？我正在运行 ubuntu 12.04 (precise)。
