在Ubuntu 15.04下安装MongoDB时无法正确执行“apt-get update”

我正在尝试在我的Ubuntu 15.04上安装MongoDB，我完成了以下步骤：

• 导入MongoDB公共GPG密钥：

sudo apt-key adv --keyserver hkp：//keyserver.ubuntu.com:80 --recv 7F0CEB10

• 创建/etc/apt/sources.list.d/mongodb-org-3.0.list列表文件以从debian wheezy存储库获取包

echo“deb http://repo.mongodb.org/apt/debian wheezy / mongodb-org / 3.0 main”| sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list

• 现在尝试执行 apt-get update 时出现此错误：

我检查了我的源文件，它包含这个：
